Ravi P Palacherla commented on OPENJPA-453:
-------------------------------------------
Started looking into the issue on openJPA trunk.
The cause of the deadlock issue on trunk is as follows:
Thread0 takes a reentrant lock inside BrokerImpl and waits to acquire
reentrant lock inside statemanagerImpl.
Thread1 takes a reentrant lock inside StatemanagerImpl and waits to acquire
reentrant lock inside BrokerImpl.
When I add debug to lock of both BrokerImpl and StateManagerImpl, here is what
I see:
[java] Thread-0 Locked java.util.concurrent.locks.reentrantl...@11410e5[locked
by thread Thread-0]
inside SMImpl org.apache.openjpa.kernel.statemanageri...@61373f
[java] Thread-0 trying to lock
java.util.concurrent.locks.reentrantl...@402af3[locked by thread Thread-1]
inside brokerImpl org.apache.openjpa.kernel.finalizingbrokeri...@b3319f
[java] Thread-1 Locked java.util.concurrent.locks.reentrantl...@402af3[locked

[java] Thread-1 trying to lock
java.util.concurrent.locks.reentrantl...@11410e5[locked by thread Thread-0]
inside SMImpl org.apache.openjpa.kernel.statemanageri...@61373f
I will continue my research and update the post as soon as I have a resolution
plan in place.
> Evicting embedded object nullifies statemanager
> -----------------------------------------------
>
> Key: OPENJPA-453
> URL: https://issues.apache.org/jira/browse/OPENJPA-453
> Project: OpenJPA
> Issue Type: Bug
> Environment: Kodo 4.1.4, Ms sql server 2005, jTDS 1.2, jdk 1.6
> Reporter: Christiaan
> Assignee: Ravi P Palacherla
> Attachments: OpenJPABug453Embedded.zip, openJPATestCase.zip,

> I am noticing the following behaviour: If evict() is called on an embedded
> object the statemanager is nullified which is in contrast to non-embedded
> objects. Subsequently, calling JDOHelper.getPersistenceManager() on the
> evicted embedded object returns null. Is this the correct behaviour?
