TLS upgrade, Stackoverflow error while using CustomHttpsSocketFactory

TLS upgrade, Stackoverflow error while using CustomHttpsSocketFactory - java

Using this link tried to upgrade to TLSv1.2. The only difference was to support all TLS till now so used this :
sslSocket.setEnabledProtocols(new String[]{"TLSv1","TLSv1.1","TLSv1.2"});
The peculiar thing was to get this error :
java.lang.StackOverflowError
at com.myorg.my.utils.Myfile$CustomHttpsSocketFactory.createSocket(Myfile.java:101)
Where Myfile.java having my contents like this, notice line 101 mentioned below :
//...non useful code above
public Myfile(){
String scheme = "https";
Protocol baseHttps = Protocol.getProtocol(scheme);
int defaultPort = baseHttps.getDefaultPort();
ProtocolSocketFactory baseFactory = baseHttps.getSocketFactory();
ProtocolSocketFactory customFactory = new CustomHttpsSocketFactory(baseFactory);
Protocol customHttps = new Protocol(scheme, customFactory, defaultPort);
Protocol.registerProtocol(scheme, customHttps);
}
class CustomHttpsSocketFactory implements SecureProtocolSocketFactory
{
private final SecureProtocolSocketFactory base;
public CustomHttpsSocketFactory(ProtocolSocketFactory base)
{
if(base == null || !(base instanceof SecureProtocolSocketFactory)) throw new IllegalArgumentException();
this.base = (SecureProtocolSocketFactory) base;
}
private Socket acceptAllTLS(Socket socket)
{
if(!(socket instanceof SSLSocket)) return socket;
SSLSocket sslSocket = (SSLSocket) socket;
sslSocket.setEnabledProtocols(new String[]{"TLSv1","TLSv1.1","TLSv1.2"});
return sslSocket;
}
#Override
public Socket createSocket(String host, int port) throws IOException
{
return acceptAllTLS(base.createSocket(host, port));
}
#Override
public Socket createSocket(String host, int port, InetAddress localAddress, int localPort) throws IOException
{
return acceptAllTLS(base.createSocket(host, port, localAddress, localPort));
}
#Override
public Socket createSocket(String host, int port, InetAddress localAddress, int localPort, HttpConnectionParams params) throws IOException
{
// The following line is 101 where the error occurs
return acceptAllTLS(base.createSocket(host, port, localAddress, localPort, params));
}
#Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException
{
return acceptAllTLS(base.createSocket(socket, host, port, autoClose));
} // ...non useful code below}
MY QUESTIONS
Seeming obvious, base.createSocket is calling its own method recursively. Cannot understand how?
Could not replicate on my local machine, these logs occur only in production. Hence how could i replicate this (Used the same Java version, tomcat version, lib version as present in production)
EDIT
As per comments the stacktrace :

If you are using JRE8 (unless you have replaced the default SunJSSE that comes with JRE8), there is a system property "jdk.tls.client.protocols". By default, whatever you mention here will be used for all client communication. I just added my comments under other post u mentioned.

I have had the same problem with java.util.concurrent.ExecutionException: java.lang.StackOverflowError
The classloader makes private final SecureProtocolSocketFactory base many times base = CustomHttpsSocketFactory and the recursive call to the method causes a StackOverflowError.
In my case my CustomHttpsSocketFactory extends SSLProtocolSocketFactory and the problem disappears

I have same problem. You will be register HTTPS protocol many many times. I think registration operation works like stack.
String scheme = "https";
Protocol baseHttps = Protocol.getProtocol(scheme);
int defaultPort = baseHttps.getDefaultPort();
ProtocolSocketFactory baseFactory = baseHttps.getSocketFactory();
ProtocolSocketFactory customFactory = new CustomHttpsSocketFactory(baseFactory);
Protocol customHttps = new Protocol(scheme, customFactory, defaultPort);
Protocol.registerProtocol(scheme, customHttps);
Protocol.registerProptocol method must call once in JVM. Each registerProtocol cause one method call after a time stack over flow.
Solution: Add a syncronized method like init and call it.
public static boolean INITIALIZED = false;
private static synchronized void init() {
if (!INITIALIZED) {
INITIALIZED = true;
String scheme = "https";
Protocol baseHttps = Protocol.getProtocol(scheme);
int defaultPort = baseHttps.getDefaultPort();
ProtocolSocketFactory baseFactory = baseHttps.getSocketFactory();
ProtocolSocketFactory customFactory = new CustomHttpsSocketFactory(baseFactory);
Protocol customHttps = new Protocol(scheme, customFactory, defaultPort);
Protocol.registerProtocol(scheme, customHttps);
}
}
...
...
init();
...

Mongo spring-data issue with java.util.Currency

Getting error "No property null found on entity class java.util.Currency"
Hi I have Document Class as
#Document
#JsonInclude(Include.NON_NULL)
public class Course {
#Id
private String id;
private String title;
private Currency curr;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public Currency getCurr() {
return curr;
}
public void setCurr(Currency curr) {
this.curr = curr;
}
}
when in make POST request to my service with data
{"title":"my title","curr":"INR"}
i get response as
{
"id": "56b0aa010364310e094c5f30",
"title": "my title",
"curr": "INR"
}
but when i make GET i get error

i'm using SpringBoot 1.3.2 and Jackons version is 2.6.5
there was similar question on stackoverflow but was deleted.
What i'm doing wrong?

The Currency type is currently not supported out of the box by the Spring Data MongoDB object mapping system. You can teach Spring Data MongoDB how to convert instances of that type by providing a custom implementation of a core Spring Converter as described in the reference documentation.
public class CustomMongoConfiguration extends AbstractMongoConfiguration {
#Bean
#Override
public CustomConversions customConversions() {
Converter<Currency, String> currencyToString = source -> source.toString();
Converter<String, Currency> stringToCurrency = source -> Currency.getInstance(source);
return new CustomConversions(Arrays.asList(currencyToString, stringToCurrency));
}
}
As the conversion to a String seems to be straight-forward, I create a ticket to be resolved in the upcoming version of Spring Data MongoDB.

Just in case someone else runs into #oliver-gierke's answer and get the NullPointerException like #kaluva
Spring's type resolver seems to have problems with the Lambda expression. Just change the bean definition to:
#Bean
public CustomConversions customConversions() {
Converter<Currency, String> currencyToString = new Converter<Currency, String>() {
#Override
public String convert(Currency currency) {
return currency.toString();
}
};
Converter<String, Currency> stringToCurrency = new Converter<String, Currency>() {
#Override
public Currency convert(String s) {
return Currency.getInstance(s);
}
};
return new CustomConversions(Arrays.asList(currencyToString, stringToCurrency));
}
(I'm sorry I could not add this answer as comment to Oliver's answer. Stackoverflow won't let me.)

How should one cast a proxy as an entity in a Spring Controller?

A REST service in a Spring Boot app is being called from an AngularJS app, but the Spring Controller is not able to perform a simple find query on the data source. Instead, the following error is thrown:
java.lang.IllegalAccessError: tried to access class demo.WebLead from class com.sun.proxy.$Proxy111
What specific changes need to be made to the code below in order for the REST service to be able to perform the query without throwing this error?
The line of code that throws the error in the Spring controller is:
WebLead wld = myrepo.findByIdlead(idl);
The same error is thrown also when the preceding line of code is altered to explicitly cast the returned entity as follows:
WebLead wld = (WebLead)myrepo.findByIdlead(idl);
The relevant parts of the Spring Boot controller and app in UiApplication.java are:
#SpringBootApplication
#Controller
#EnableJpaRepositories(basePackages = "demo", considerNestedRepositories = true)
public class UiApplication extends WebMvcConfigurerAdapter {
#Autowired
private WebLeadRepository myrepo;// {}
#RequestMapping(value = "/some-url", method = RequestMethod.POST)
public #ResponseBody ResultMessage submitPhone(HttpSession session, #RequestBody ResultPhone rphon) {
ResultMessage resmess = new ResultMessage("phonetest");
try{
Long idl = Long.parseLong(rphon.getWleadid());
WebLead wld = (WebLead)myrepo.findByIdlead(idl);
return resmess;
} catch(Exception e){return resmess;}
}
//other stuff
}
WebLeadRepository.java is:
public interface WebLeadRepository extends JpaRepository<WebLead, Long> {
WebLead findByIdlead(Long idl);
}
WebLead.java is:
#Entity
class WebLead {
#GeneratedValue
#Id
private Long idlead;
private String firstname;
private String lastname;
private String emailaddress;
#Column(name="creation_date")
private DateTime creationdate;
public Long getIdlead(){return this.idlead;}
public String getFirstname(){return firstname;}
public void setFirstname(String fn){this.firstname = fn;}
public String getLastname(){return lastname;}
public void setLastname(String ln){this.lastname = ln;}
public String getEmailaddress(){return emailaddress;}
public void setEmailaddress(String em){this.emailaddress = em;}
public DateTime getCreationdate(){return creationdate;}
public void setCreationdate(DateTime ad){creationdate=ad;}
}
The complete stack trace is:

Your WebLead class is package-local (because you omitted any acccess level modifier). But Spring Data creates a proxy for the repository interface, and that proxy (com.sun.proxy...) is in another package, so it cannot acccess your entity class. Change the modifier of WebLead to public, then it should work.

Customizing LdapUserDetails in Spring Security 4.0.1.RELEASE

I am building a Spring Boot app with Spring Security that is using ldap for authentication. I am trying to add a Person object to a custom LdapUserDetails object that can be accessed from a controller, but am having trouble calling that custom LdapUserDetails object.
My implementation of LdapUserDetails is below:
public class DirXUserDetails implements LdapUserDetails {
private final Person user;
public DirXUserDetails(Person user) {
this.user = user;
}
#Override
public Collection<GrantedAuthority> getAuthorities() {
Person.SecurityRole[] roles = user.getRole();
if (roles == null) {
return Collections.emptyList();
}
return Arrays.<GrantedAuthority>asList(roles);
}
#Override
public String getPassword() {
return user.getPassword();
}
#Override
public String getUsername() {
return user.getUserId();
}
#Override
public boolean isAccountNonExpired() {
return true;
}
#Override
public boolean isAccountNonLocked() {
return true;
}
#Override
public boolean isCredentialsNonExpired() {
return true;
}
#Override
public boolean isEnabled() {
return true;
}
public Person getUser() {
return user;
}
#Override
public String getDn() {
return null;
}
}
Here is my UserDetailsServiceImpl class:
#Component
public class DirXUserDetailsImpl implements DirXUserDetailsService {
Logger log = Logger.getLogger(DirXUserDetailsImpl.class.getName());
#Autowired
private PersonService personRepository;
#Autowired
private Session session;
#Override
public DirXUserDetails loadUserByUsername(String userId) throws UsernameNotFoundException {
log.info("Load user: " + userId);
final Person user = personRepository.findByUserId(userId);
if(user == null) {
log.info("Username not found: " + userId);
throw new UsernameNotFoundException("Username not found: " + userId);
}
return new DirXUserDetails(user);
}
Here is my implementation of UserDetailsService:
public interface DirXUserDetailsService extends UserDetailsService {
#Override
public DirXUserDetails loadUserByUsername(String userId) throws UsernameNotFoundException;
Person getUserFromSession();
}
And finally the controller:
#RestController
public class HomeController {
static Logger log = Logger.getLogger(HomeController.class.getName());
#Autowired
PersonService personService;
#RequestMapping("/")
public ModelAndView dashboard(Authentication authentication) {
DirXUserDetails dirXUserDetails = (DirXUserDetails) authentication.getPrincipal();
ModelAndView mav = new ModelAndView();
mav.setViewName("dashboard");
mav.addObject("user", dirXUserDetails.getUser());
return mav;
}
}
This error comes when calling DirXUserDetails dirXUserDetails = (DirXUserDetails) authentication.getPrincipal();:
java.lang.ClassCastException: org.springframework.security.ldap.userdetails.LdapUserDetailsImpl cannot be cast to org.directoryx.service.DirXUserDetails

After debugging I see that loadUserByUsername() is being called in DirXUserDetailsImpl and DirXUserDetails is being returned to Spring Security, but when trying to call authentication.getPrincipal() in the controller it returns an LdapUserDetailsImpl object and not a DirXUserDetails object.
I have looked at the Spring Security 4.0.1.RELEASE docs as well as many other Spring Security articles but couldn't find anything on this. How can I access DirXUserDetails from the controller?

Looks like I was going about this the wrong way. The UserDetailsService used is not what Spring Security's LdapAuthenticationProvider uses to create the UserDetails, it is actually an implementation of an LdapUserDetailsMapper. The following code solved my issue:
#Component
public class CustomUserDetailsMapper extends LdapUserDetailsMapper {
#Override
public CustomUserDetails mapUserFromContext(DirContextOperations dirContextOperations, String userId, Collection<? extends GrantedAuthority> collection) {
return new CustomUserDetails();
}
}
And set the UserDetailsMapper in the Spring Security Config file like this:
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
CustomUserDetailsMapper userDetailsMapper;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.
ldapAuthentication().userDnPatterns("cn={0}").userDetailsContextMapper(userDetailsMapper)
.contextSource(contextSource())
}

Cannot Initialize a class using the Singleton Method

I created a class that gets an instance of a Database connection. However I am getting an error saying the calling class is null. I will post my error below.
Now I have a working and non working version of this code. I first just jammed everything into a single class to get it up and running then started to clean it up which is when I ran into issues.
This class "createJobTicket" calls the instance of DataBaseConnectionDAO
public class createJobTicket {

You can notice that the following is commented out:
//private java.sql.Connection conn = null;
//private java.sql.Statement stmt = null;
This is because if I my IDE said:
Cannot make a static reference to the non-static field conn
Cannot make a static reference to the non-static field stmt
My DataBaseConnectionDAO looks like the following:
public class DataBaseConnectionDAO {
#Inject
private static Environment env;
private static DataBaseConnectionDAO instance;
// Step 1: JDBC props
String DB_URL = env.getProperty("spring.datasource.url");
String USER = env.getProperty("spring.datasource.username");
String PASS = env.getProperty("spring.datasource.password");
java.sql.Connection conn = null;
java.sql.Statement stmt = null;
private DataBaseConnectionDAO() { }
public static DataBaseConnectionDAO getInstance() {
if (instance == null) {
synchronized (DataBaseConnectionDAO.class) {
if (instance == null) {
instance = new DataBaseConnectionDAO();
}
}
}
return instance;
}
public java.sql.Connection getConnection() throws ClassNotFoundException,
SQLException {
Class.forName("com.mysql.jdbc.Driver");
if (conn == null) {
conn = DriverManager.getConnection(DB_URL, USER, PASS);
}
return conn;

You need to start by understanding what this error message means:
java.lang.NoClassDefFoundError: Could not initialize class com.htd.web.rest.util.createJobTicket
When the JVM loads a class, it will complete any static initialization for that class, i.e. assign any values given to static fields and run any static { ... } blocks. As this involves running Java code, this process may cause an exception to be thrown. If an exception is thrown during a class's static initialization, the class loading will fail. Java will wrap the exception in an ExceptionInInitializerError and throw that. If you make a second attempt to load the same class, Java will flatly refuse to load it, and instead throw a NoClassDefFoundError with message Could not initialize class ....
As this is the error you are seeing, I can only conclude that your createJobTicket class is failing its static initialization, and that the exception stacktrace above is not from the first time you attempt to use the createJobTicket class. If, for example, your application is a web application, try restarting the web application container, trying again and seeing if you get a different error first time around.
The static initialization for your createJobTicket class is the following line:
private static DataBaseConnectionDAO databaseConnection = DataBaseConnectionDAO.getInstance();
So your DataBaseConnectionDAO.getInstance() method must be throwing an exception.
The best way to avoid static initialization issues like this is to avoid static initialization altogether. For example, in the following, we create a method getDatabaseConnection() which sets the databaseConnection field if it hasn't already been set, and additionally calls the DAO to return a JDBC Connection object:
private static DataBaseConnectionDAO databaseConnection;
private static java.sql.Connection getDatabaseConnection() {
if (databaseConnection == null) {
databaseConnection = DataBaseConnectionDAO.getInstance();
}
return databaseConnection.getConnection();
}
public static HSSFWorkbook getWorkbook(HSSFWorkbook workbook, Long id, Environment env){
try{
java.sql.Connection conn = getDatabaseConnection();
// ...
This approach should stop your createJobTicket class from failing to complete static initialization. However, please do not expect your code to immediately start working after doing this. The change above goes no way to fix the exception that causes the static initialization to fail. All it does is to make sure this exception only gets thrown after the class has been statically initialized. If you then attempt to run your code, you should hopefully see the actual exception in your log, instead of the NoClassDefFoundError.
So, why would your DataBaseConnectionDAO.getInstance() method be throwing an exception? My best guess is this:
#Inject
private static Environment env;
A few searches suggest that you can't use Spring to inject values into static fields like this, so perhaps you are getting a NullPointerException trying to look up values in an environment that is null. However, I haven't looked into this fully so I don't guarantee that this actually is the problem.

TLS upgrade, Stackoverflow error while using CustomHttpsSocketFactory - java

If you are using JRE8 (unless you have replaced the default SunJSSE that comes with JRE8), there is a system property "jdk.tls.client.protocols". By default, whatever you mention here will be used for all client communication. I just added my comments under other post u mentioned.
