EntityManager

ynusis Mar 22, 2012 10:19 AM

Hi,

I get some strange exception when I Inject the EntityManager:

@Singleton
@Startup
public class TestJMS {


rivate Queue test;
  
          @Inject
          private EntityManager em;
  
          @PostConstruct
          public final void setUp() {
                    System.out.println(this.em.isOpen());
          }
}

public class Resources {


   @SuppressWarnings("unused")
   @Produces
   @PersistenceContext(unitName = "pool")
   private EntityManager em;
   
   @Produces
   public Logger produceLog(InjectionPoint injectionPoint) {
      return Logger.getLogger(injectionPoint.getMember().getDeclaringClass().getName());
   }
}

The Exception looks like this:

Any ideas?

1. Re: duplicate class definition for name: org/jboss/weldx/persistence/EntityManager

This sounds like a race condition caused by an attempt to load the same class twice.

Maybe you can get more information by enabling TRACE logging and recreate the error, then look at the TRACE log output (as7/standalone/log/server.log) for clues as to which threads loaded the same class (org.jboss.weldx.persistence.EntityManager) and why.

You probably could get more selective than turning trace on for everything, but in this case, more information is better (assuming you will be searching for "org.jboss.weldx.persistence.EntityManager" via an editor search feature).

What does you application layout looks like?
can you post output of jar tf <name of your deplyoment>
my first guess would be that you are bunding weld-core jar inside your app.

Hi. I attached my log file. As far as I understand the output there are no problems?

In the server.log, I see that different threads are looking for org.jboss.weldx.persistence.EntityManager and not finding. The next question is, will they atomically define org.jboss.weldx.persistence.EntityManager or will multiple threads try to define it.

Note the thread names involved with looking for this class (will shorten to just the number part ignoring "msc service thread"). 1-3, 1-2, 1-8, 1-1

Hmm, interesting that thread ".... 1-8" soon again doesn't see the generated class. I'm not sure what this means yet. Maybe something went wrong with defining this class before and it didn't really get defined or maybe it is defined on the wrong classloader (different than the one we are looking for the class on).

08:03:32,465 TRACE [org.jboss.modules] (MSC service thread 1-8) Class org.jboss.weldx.persistence.EntityManager$713319412$Proxy$_$$_Weld$Proxy$ not found from Module "deployment.server-ear.ear.server-ejb-1.0.0-SNAPSHOT.jar:main" from Service Module Loader

Jumping ahead to the actual duplicate cls def errors. Of the threads previously thought to be looking for the class (1-3, 1-2, 1-8, 1-1). The duplicate class definied error happened on three out of four of those threads. This sounds like a race condition bug to me.

What do others think?

Hi,

can you remove geronimo-spec-jms-1.1-rc4.jar and javassist-3.12.1.GA.jar from your lib.

jms spec is added automaticly as dependancy and there is no need to add it yourself.
for javassist if there is real need in your application for it, then i would recomend you importing it via dependancies in MANIFEST.MF or jboss-deployment-structure.xml

as javaassit inside your app could produce errors like this, as classes are javaassit enhanced on server and then used in application.

I jumped further into the problem and found out, that the problem occurs when I try to deploy more than one @Startup @Singleton Bean with an Injected EntityManager.

The two libraries are dependencies of some other projects. So I will figure out how " importing it via dependancies" works...

EDIT: Removed the libs. Problem still exists.

Hi,
Can you update weld to 1.1.6.Final (released this week)
or just use nightly build of as7.1.2 (weld update was included yesterday)

as this seems to be an issue in weld.

Weld 1.1.6.Final doesnt seem to work. https://community.jboss.org/message/726213#726213 also have the Weld problem.
Nightlybuild as far as https://ci.jboss.org/jenkins/job/JBoss-AS-7.x-latest/ is the korrekt location seem to be pretty old.

Hi,

my 50cents as I have the same problem occurrence. I have tried to build latest as7 from today (27th March) to include weld 1.1.6.Final (I can report too that Jenkins is stil on strike).

Test case is like this:

- I have abstract web filter in ejb jar which injects some JPA based repositories
- some different parts of (web)app create an impl of this filter with various @WebFilter annotation parameters
- jboss is freshly started, and in 1 out of 5 cases, when some servlet is hit via this filter I got The error
- seems that only first one hit has a problem, all the next are ok

I got the above error even with weld 1.1.6, stack trace included if of any help.

This is a race-condition in AS7, which Stuart already fixed, afaik.

It sounds like this issue was already fixed and is actually an AS issue. Not sure why the issue was opened in AEROGEAR jira. I'm going to reject it, but please feel free to reopen and move to the appropirate project.
