[jboss-dev-forums] [Design of JBoss jBPM] - AbstractDbTestCase -> deleteProcessDefinition -> hibernate c

Hi all. I have some very strange problems when writing Tests for Commands. I extended AbstractDbTestCase. The tests worked standalone in Eclipse, but when running the whole test suite with Maven, other tests failed. Okay, problems with test isolation. So lets clean up after my tests. Hence I deleted the ProcessDefinitions afterwards.Now my tests throw Exceptions :-/ I stripped it down to the following code, which results in a exception what I don't understand completly yet. Anybody an idea? | public class WhateverTest extends AbstractDbTestCase | { | public void testDBProblem() { | String xml = "<process-definition name='Test'>" | +" <start-state name='start'>" | +" <transition to='end' />" | +" </start-state>" | +" <end-state name='end' />" | +"</process-definition>"; | ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(xml); | jbpmContext.deployProcessDefinition(processDefinition); | ProcessInstance processInstance = processDefinition.createProcessInstance(); | Token token = jbpmContext.loadTokenForUpdate(processInstance.getRootToken().getId()); | jbpmContext.getGraphSession().deleteProcessDefinition(processDefinition.getId()); | } | } | The Exception is | org.jbpm.persistence.JbpmPersistenceException: hibernate commit failed | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:223) | at org.jbpm.svc.Services.close(Services.java:236) | at org.jbpm.JbpmContext.close(JbpmContext.java:136) | at org.jbpm.db.AbstractDbTestCase.closeJbpmContext(AbstractDbTestCase.java:193) | at org.jbpm.db.AbstractDbTestCase.commitAndCloseSession(AbstractDbTestCase.java:116) | at org.jbpm.db.AbstractDbTestCase.tearDown(AbstractDbTestCase.java:71) | at junit.framework.TestCase.runBare(TestCase.java:130) | at junit.framework.TestResult$1.protect(TestResult.java:106) | at junit.framework.TestResult.runProtected(TestResult.java:124) | at junit.framework.TestResult.run(TestResult.java:109) | at junit.framework.TestCase.run(TestCase.java:118) | at junit.framework.TestSuite.runTest(TestSuite.java:208) | at junit.framework.TestSuite.run(TestSuite.java:203) | at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) | at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) | Caused by: org.hibernate.AssertionFailure: null id in org.jbpm.graph.exe.ProcessInstance entry (don't flush the Session after an exception occurs) | at org.hibernate.event.def.DefaultFlushEntityEventListener.checkId(DefaultFlushEntityEventListener.java:55) | at org.hibernate.event.def.DefaultFlushEntityEventListener.getValues(DefaultFlushEntityEventListener.java:164) | at org.hibernate.event.def.DefaultFlushEntityEventListener.onFlushEntity(DefaultFlushEntityEventListener.java:120) | at org.hibernate.event.def.AbstractFlushingEventListener.flushEntities(AbstractFlushingEventListener.java:196) | at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:76) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) | at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) | at org.jbpm.persistence.db.DbPersistenceService.commit(DbPersistenceService.java:262) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:218) | ... 18 more | The problem is the jbpmContext.loadTokenForUpdate, if I remove the statement, the test works... But that should work because of Hibernate SessionCache, or am I totally wrong here? Thanks for any help or hints!
