Description Jan Martiska 2012-11-26 14:50:37 UTC

project_key: JBPAPP6

When a client invokes a EJB2 stateful session bean, which is being destroyed right at the same time, a race condition sometimes leads to a NullPointerException.

The scenario when this error occurs:
1. the bean is in a passivated state
2. client invokes a method on it
3. activation routine is run for the instance
4. however, it seems that even during activation procedure, container sometimes still decides to expire and remove it
5. this leads to a NullPointerException

I set the bean's stateful timeout to 1 millisecond to increase the chance for this to happen.

{noformat}

Had the bean expired properly BEFORE the invocation, it would have thrown a NoSuchObjectException, which is ok according to spec. 

A reproducer is available at: https://github.com/jmartisk/jboss-as/tree/jbqa-6319-stateful-expiration , test=org.jboss.as.test.clustering.extended.ejb2.stateful.passivation.StatefulPassivationExpirationTestCase . The test is part of clustering testsuite, but I suppose this is not a clustering-specific error.

(this is forked from upstream 7.2 branch, but you can run it against EAP 6.0.1, just edit testsuite/integration/clust/src/test/config/arq/arquillian.xml and change the port offset argument from jboss.port.offset to jboss.socket.binding.port-offset so the two EAPs will not clash).

Can you please paste the complete NPE stacktrace here too?

Assigning jpai EJB issues to david.lloyd. Please re-assign to Cheng or others as needed.

Comment 7 Dominik Pospisil 2014-05-14 21:35:24 UTC

The issue affect also EJB3 SFSB beans and also non passivating beans. However with not passivating beans it is harder to reproduce.

Comment 9 Dominik Pospisil 2014-05-16 07:48:58 UTC

The issue seem to be caused by possible race condition in both PassivatingBackingCacheImpl and NonPassivatingBackingCacheImpl. The cache impl get methods cancel instance expiration and passivation until release method is called. However the cancelExpirationPassivation(key) does not block and if the cache entry expiration has already bean triggered, it is not canceled and could be executed between get/release.

Comment 10 Jan Martiska 2014-07-07 13:20:36 UTC

The test still fails with NPE intermittently, tried with 6.3.0.ER8 and I see a failure in one of every ~30 runs, I estimate. The NPE I see now is a little bit different though:

Comment 11 Dominik Pospisil 2014-07-28 07:02:46 UTC

I was unable to reproduce the issue with both ER8 and 6.x branch. QA is unable to reproduce with 6.x as well. Please reopen if the issue could be reproduced with 6.x or latest ER build.
