Jbpm 6.0.0.beta2 error disposing ksession when commiting transaction

created by Pablo Zamudio in jBPM Development - View the full discussion

We are testing Jbpm 6.0.0.beta2 and we get an error when working inside JBoss7, in a CMT environment.

We are using a PerRequestRuntimeManager, so with the new apis, in a CMT environment, as soon as the transaction is commited, DisposeSessionTransactionSynchronization should dispose ksession and delete it from database.

The error happens when the tx sync tries to delete ksession from db, because it tries to join the current transaction, which has been closed, so errors of transaction closed appears.

Looking at tests cases in source code, the test PerRequestRuntimeManagerTest.testCreationOfSessionWithinTransaction() has exactly the problem i am describing. The test gives green results, but in console appears the exceptions as warnings. When running over JBoss7, this exceptions turns to errors, because the server tries to make rollback of the current transaction (which is already commited).

The exact exception in testcase is:
