[jboss-user] [JBoss Seam] - Weird async/timer related error, collection not processed on

Well, I understand this is coming out of hibernate. But, I just hadn't seen it before using the previously working code on the new async timer stuff. Same code works fine without using the async timer. I.E. just inlining the same method call synchronously works fine. Using the async timer around the same method call, however, I'm getting errors like below, and the txn is rolled back: | 17:19:15,861 ERROR [AssertionFailure] an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session) | org.hibernate.AssertionFailure: collection [x.x.Membership.permissionAssoc] was not processed by flush() | at org.hibernate.engine.CollectionEntry.postFlush(CollectionEntry.java:205) | at org.hibernate.event.def.AbstractFlushingEventListener.postFlush(AbstractFlushingEventListener.java:333) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:28) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) | at org.hibernate.ejb.AbstractEntityManagerImpl$1.beforeCompletion(AbstractEntityManagerImpl.java:515) | at org.jboss.tm.TransactionImpl.doBeforeCompletion(TransactionImpl.java:1491) | at org.jboss.tm.TransactionImpl.beforePrepare(TransactionImpl.java:1110) | at org.jboss.tm.TransactionImpl.commit(TransactionImpl.java:324) | at org.jboss.tm.TxManager.commit(TxManager.java:240) | at org.jboss.aspects.tx.TxPolicy.endTransaction(TxPolicy.java:175) | at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:87) | at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:197) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.aspects.security.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:77) | at org.jboss.ejb3.security.Ejb3AuthenticationInterceptor.invoke(Ejb3AuthenticationInterceptor.java:131) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:47) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.asynchronous.AsynchronousInterceptor.invoke(AsynchronousInterceptor.java:106) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.stateless.StatelessContainer.callTimeout(StatelessContainer.java:150) | at org.jboss.ejb.txtimer.TimerImpl$TimerTaskImpl.run(TimerImpl.java:524) | at java.util.TimerThread.mainLoop(Timer.java:512) | at java.util.TimerThread.run(Timer.java:462) | The collection "permissionAssoc" referenced above is not consistently the collection (on repeated tests) that it references in the flush error. It doesn't seem to matter what collection it is. It's referenced at least 3 other collections on other tests, across various other entity classes. Here's permissionAssoc: | @OneToMany(mappedBy="membership", cascade=CascadeType.ALL, fetch=FetchType.LAZY) | protected Set<MembershipPermission> getPermissionAssoc() { | if (permissionAssoc == null) permissionAssoc = new HashSet<MembershipPermission>(); | return permissionAssoc; | } | protected void setPermissionAssoc(Set<MembershipPermission> permissionAssoc) { | this.permissionAssoc = permissionAssoc; | } | I most definitely do not access the private var "permissionAssoc" directly anywhere in the class. Any ideas on where to look / try? Using 4.0.5. Strange that regular Seam use of the same code would work fine, but once it's in a timer it blows up.
