What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 7 years ago.
I'm struggling with some code which systematicly fails on jenkins, but passes without issues on my machine, of course.
public static FaultException getFaultException(String faultCode, String faultString) {
LOGGER.debug("start getFaultException");
Fault fault = new Fault();
fault.setFaultCode(faultCode);
fault.setFaultString(faultString);
LOGGER.debug("Returning new FaultException");
FaultException fex = new FaultException("Fault exception", fault);
LOGGER.debug("fex is ", fex);
try {
if (fex == null) {
LOGGER.debug("getFaultException fex is null");
}
}catch(NullPointerException nex) {
LOGGER.debug("catched npe ", nex);
}
LOGGER.debug("fex class is " + fex.getClass().getCanonicalName());
LOGGER.debug("fex built in getFaultException");
return fex;
}
The code you see will display on jenkins catched npe + the null pointer exception, and will re-trigger a npe on the next line. So basicly i am having a npe while checking if an object is null (the if (fex == null) line is the culprit).
However the LOGGER.debug("fex is ", fex); line will successfully dump a FaultException object.
How can this be?
The jenkinks machine runs openjdk 1.7.0_85-b01, my machine is a windows machine with 1.7.0_80. Also, the FaultException class is a generated class, with a #WebFault annotation, but i compared the resulted bytecode on the two machines and are the same. (except paths and stuff like that)
Thanks for looking!
UPDATE, the log file:

UPDATE 2: the FaultException.java file:
#WebFault(name = "Fault", targetNamespace = "urn:dslforum-org:cwmp-1-0")
public class FaultException extends Exception {
private [censored].Fault fault;
public FaultException() {
super();
}
public FaultException(String message) {
super(message);
}
public FaultException(String message, Throwable cause) {
super(message, cause);
}
public FaultException(String message, [censored].Fault fault) {
super(message);
this.fault = fault;
}
public FaultException(String message, [censored].Fault fault, Throwable cause) {
super(message, cause);
this.fault = fault;
}
public [censored].Fault getFaultInfo() {
return this.fault;
}
}
what do you expect?
you are using fex after your null check normaly:
try {
if (fex == null) {
LOGGER.debug("getFaultException fex is null");
}
}catch(NullPointerException nex) {
LOGGER.debug("catched npe ", nex);
}
HERE --> LOGGER.debug("fex class is " + fex.getClass().getCanonicalName());
that must leads to a NPE because fex can only be null if your first condition was true.
That would be make more sense:
if (fex == null) {
LOGGER.debug("getFaultException fex is null");
}else{
LOGGER.debug("fex class is " + fex.getClass().getCanonicalName());
LOGGER.debug("fex built in getFaultException");
}
return fex;
btw. try catch NPE is not necessary here. it cannot be thrown.
Would be the LOGGER null the first line of your method would throw a NPE.

I'm trying to send objects using Java RMI in a JavaFX 2 project, but when the following code runs it returns a NotSerializableException.
My Admin class is Serializable and so is the super class. However it seems the exception is pointing towards the JavaFX SimpleIntegerProperty fields inside the Admin class.
I don't know what to do from here as the class being sent via RMI is serializable. Any help much appreciated.
ObservableList<Admin> data = null;
try
{
data = FXCollections.observableArrayList(Main.docServer.getAllAdmins());
}
catch (RemoteException e)
{
e.printStackTrace();
}

the class being sent via RMI is serializable
It's only serializable if it extends Serializable or Externalizable and all of its non-static non-transient member variables do so as well, and so on recursively until closure. In this case you clearly have one of type javafx.beans.property.SimpleIntegerProperty, which as the exception tells you isn't serializable:
java.io.NotSerializableException: javafx.beans.property.SimpleIntegerProperty
So any class that refers to it, directly or indirectly, isn't serializable either.
You may mark a member variable not to be serialized. And add to class new int field.
private int variableInt = 0;
private transient IntegerProperty variable;
public IntegerProperty variableProperty()
{
if(variable == null)
{
variable = new SimpleIntegerProperty();
variable.set(variableInt);
}
return variable;
}
public void setVariable(int variable)
{
if(this.variable != null)
this.variable.set(variable);
variableInt = variable;
}
public int getVariable()
{
if(variable == null)
return variableInt;
else
return variable.get();
}

What do I wrong?
If to remove following row:
whenNew(StringWriter.class).withNoArguments().thenReturn(stringWriterMock);
code becomes working...
What the magic?
The exception is thrown when the static initializer of IOUtils is executed, which looks like this (version 2.4):
static {
// avoid security issues
StringBuilderWriter buf = new StringBuilderWriter(4);
PrintWriter out = new PrintWriter(buf); //<-- kaboom here
out.println();
LINE_SEPARATOR = buf.toString();
out.close();
}
The NullPointerException is thrown down the stack while invoking new PrintWriter(buf) because the parameter (buf) is null.
I suspect your remaining test code modifies the code so that buf is assigned a value of null. Did you mock the Constructor of StringBuilderWriter for some reason?
I am experiencing a strange error. I have an Eclipse 3.7.2-based RCP application.
When starting it from my run configuration, it throws an InvocationTargetException which is caused by an SWTError (stacktrace below). In the stacktrace there is the message "Could not instantiate splash", however, the splash is shown without any problems.
The only line of code from my own code base in the stacktrace is from the Application.class:
int returnCode = PlatformUI.createAndRunWorkbench(display,
new ApplicationWorkbenchAdvisor());
It is true, in ApplicationWorkbenchAdvisor I have some dubious SWT-based code calling, e.g., the internal (evil!) IDEWorkbenchPlugin:
#Override
public void initialize(IWorkbenchConfigurer configurer) {
super.initialize(configurer);
IDE.registerAdapters();
final String ICONS_PATH = "icons/full/";
final String PATH_OBJECT = ICONS_PATH + "obj16/";
Bundle ideBundle = Platform.getBundle(IDEWorkbenchPlugin.IDE_WORKBENCH);
declareWorkbenchImage(configurer, ideBundle, IDE.SharedImages.IMG_OBJ_PROJECT,
PATH_OBJECT + "prj_obj.gif", true);
declareWorkbenchImage(configurer, ideBundle, IDE.SharedImages.IMG_OBJ_PROJECT_CLOSED,
PATH_OBJECT + "cprj_obj.gif", true);
}
public IAdaptable getDefaultPageInput() {
IWorkspace workspace = ResourcesPlugin.getWorkspace();
return workspace.getRoot();
}
public WorkbenchWindowAdvisor createWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {
return new ApplicationWorkbenchWindowAdvisor(configurer);
}
public String getInitialWindowPerspectiveId() {
return PERSPECTIVE_ID;
}
private void declareWorkbenchImage(IWorkbenchConfigurer configurer_p, Bundle ideBundle, String symbolicName,
String path, boolean shared) {
URL url = ideBundle.getEntry(path);
ImageDescriptor desc = ImageDescriptor.createFromURL(url);
configurer_p.declareImage(symbolicName, desc, shared);
}
However, even when I comment out that code and leave the initialize() method with only the call super.initialize(configurer);, the application starts just fine, but still throws the errors...
