"ClientAbortException" on host, "SocketException: connection rest" on client

I have one service client calling a restful endpoint on another of my services.
The client is getting a "SocketException: connection reset" exception, while the host service is throwing an "IOException: APR error: -730054" (or in other words, a Client Abort exception) but the actions it was performing still complete properly and it tries to return a response code of 200 before the exception is thrown.
So the host service thinks that the calling client service closed the connection, but the client thinks that the host service closed the connection.
I do not have this problem in all environments, so it seems obvious that something in the new environment between the two services (firewall and/or proxy) is closing the connection. Unfortunately for me, I'm not savvy when it comes to these issues (Applications Developer).
I am running Java1.8.0_91-b15 with Tomcat 8.0.26 in a windows server 2012 R2 (for both services).
Each application is using SpringBoot 1.3.8.RELEASE to create the war file being deployed to Tomcat (yes I know, make jar not war, but it is what it is) and the Client is using springs RestTemplate to call the other service.
Another weird thing is that each request that is failing in this manner has the same total byte size of 80200 bytes.

What Caused It
It ended up being an issue with network overload from the company database replication traffic. Since the replication had been set as highest priority, but no limits were set on it's traffic during peak business hours, it was taking up all the network resources. This meant the client could connect to the service initially, but when the database would be updated it would kick off replication as well. That meant that the response could not get through, and the client could not ping back.
So basically ...
If you see these two errors in their respective locations, it means that neither application is at fault for disconnecting, but something is preventing the client and the service from communicating. You and your network administrators need to evaluate what could be in the middle of the two that is causing your problem.

I am creating a Word document which has a table in it.
Following is the code for it:

An error is thrown at line 41.

I have included two parameters rows and columns while initializing.
Line 41. XWPFTable table = document.createTable(2,2);
And also removed the dependency as build was failing with this dependency:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>ooxml-schemas</artifactId>
<version>1.1</version>
</dependency>
This solved the error.

I think it's lack of jar package.

ClassCastException when saving object in Spring redis session

Using spring boot 1.3.0.RC1, we used #EnableRedisHttpSession to enable RedisHttpSession.
We tried to save an object in session :
ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
HttpSession session = attr.getRequest().getSession();
TestUser testObject = new TestUser();
session.setAttribute("test", testObject);
TestUser implements Serializable.
When we try to get this session object from other method, we receive nested exception is java.lang.ClassCastException: test.common.session.security.TestUser cannot be cast to test.common.session.security.TestUser

I am facing similar Issue. Based on the discussion going on here https://github.com/spring-projects/spring-boot/issues/4565 it seems DevTools are causing some issue.
I removed spring-boot-devtools and it is working fine.

Does System.out.println() have a side effect in Java?

When I put println() inside a DAO method, the program works when I call the update method.
#Override
public Post getPostById(int id) {
Session session = DatabaseConnection.connect().openSession();
Post post = (Post) session.load(Post.class, new Integer(id));
System.out.println("debug " + post);
session.close();
return post;
}
When I don't, it gives me an error
#Override
public Post getPostById(int id) {
Session session = DatabaseConnection.connect().openSession();
Post post = (Post) session.load(Post.class, new Integer(id));
session.close();
return post;
}
Here's the error msg:
SEVERE: Invalid property 'account' of bean class [com.personal.pojo.Post_$$_jvsta3d_0]: Getter for property 'account' threw exception; nested exception is java.lang.reflect.InvocationTargetException

Here's the method I am calling:
#RequestMapping("/edit/{id}")
public String editPost(#PathVariable("id") int id, Model model)
{
model.addAttribute("post", RegistryDAO.getPostDAO().getPostById(id));
return "edit";
}
How is that even possible?

Does System.out.println() have a side effect in Java?
Yes. One side-effect is that it produces output!
But more importantly (in your situation) it can change the timing and thread scheduling. If you have a concurrency bug elsewhere in your code, a println can prevent the bug from happening.
The error message is not very informative, but it seems to be saying that some object (bean) has an account property, and the getter has failed. If you can get the full exception stacktrace (e.g. from the logfiles), there should be more clues there.
This is the root exception message (from the stacktrace that you added):
Caused by: org.hibernate.LazyInitializationException:
could not initialize proxy - no Session
Jim Garrison has identified a number of possible duplicates based on that message; see comment above. Check those first.
Could it be that session.close(); inside getPostById is closing the session prematurely?
Yes it could be. You need to be consistent on how you handle (open and close) sessions.
Note that if you "cache" objects created using a short-term Session, then they become disconnected when the Session is closed. If the objects are lazy initialized, this can lead to problems. I found this explanation (in Altassian documentation):
Hibernate Sessions
Sessions are a Hibernate construct used to mediate connections with the database.
The session opens a single database connection when it is created, and holds onto it until the session is closed. Every object that is loaded by Hibernate from the database is associated with the session, allowing Hibernate to automatically persist objects that are modified, and allowing Hibernate to implement functionality such as lazy-loading.
Disconnected Objects
If an object is evicted from its session (for example via a clear, see below), or the session is closed while the object is still kept alive, the object is "disconnected" from the session. A disconnected object will continue to work so long as you don't perform any operation that it needs to go back to the database for, such as accessing a lazily-loaded collection.
If you see a LazyInitializationException, it means that a Hibernate-managed object has lived longer than its session.
Managed objects are not portable between sessions. Trying to load an object in one session then save it into another session will also result in an error. (You can use Session.load() or Session.get() to re-introduce an object to a new session, but you're much better off fixing whatever problem is causing you to try to move objects between sessions in the first place.

Spring Data MongoDB NearQuery EnumList IllegalArgumentException

I'm getting an IllegalArgumentException while doing a NearQuery-Search with a Criteria. Doing a NearQuery-Search without the Criteria works fine.
The Criteria works with a normal Query.

This is the source:
Criteria criteria = Criteria.where("testList").is(MyTestEnum.TEST);
NearQuery nq = NearQuery.near(new Point(req.getRangeLat(), req.getRangeLng())).spherical(true).maxDistance(new Distance(req.getRangeKm(), Metrics.KILOMETERS));
nq.query(new Query(criteria));
The field testList is a List which can hold multiple MyTestEnums.
Does anyone know how to get my NearQuery with this Criteria to work?
