Hi
We have stuck problem with for instance the following threads, how do deferredlock happen ?
Do they happen when we call get-methods on jpa-entities ? Because our method getKursusDetails2 only calls get methods, and also call find-method to find entity, it also calls: Aktivitet aktivitet = new Aktivitet(); Where Aktivitet is a jpa-entity, but we don’t persist or merge this entity, it is only used temporary as a pojo in the webservice-method – do this give a problem
when calling flush ? /regards Mejar Thread-15 "[STUCK] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'" <alive, suspended, sleeping, priority=1, DAEMON> { java.lang.Thread.sleep(Thread.java:???) org.eclipse.persistence.internal.helper.ConcurrencyManager.releaseDeferredLock(ConcurrencyManager.java:429) org.eclipse.persistence.internal.identitymaps.CacheKey.releaseDeferredLock(CacheKey.java:348) org.eclipse.persistence.internal.helper.WriteLockManager.releaseAllAcquiredLocks(WriteLockManager.java:454) org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.mergeChangesIntoParent(UnitOfWorkImpl.java:3237) org.eclipse.persistence.internal.sessions.RepeatableWriteUnitOfWork.mergeChangesIntoParent(RepeatableWriteUnitOfWork.java:348) org.eclipse.persistence.internal.sessions.UnitOfWorkImpl.mergeClonesAfterCompletion(UnitOfWorkImpl.java:3423) org.eclipse.persistence.transaction.AbstractSynchronizationListener.afterCompletion(AbstractSynchronizationListener.java:187) org.eclipse.persistence.transaction.JTASynchronizationListener.afterCompletion(JTASynchronizationListener.java:79) weblogic.transaction.internal.ServerSCInfo.doAfterCompletion(ServerSCInfo.java:1039) weblogic.transaction.internal.ServerSCInfo.callAfterCompletions(ServerSCInfo.java:989) ^-- Holding lock:
