Taking the advice of Burkhard and Dennis, I now (think) I have exclusive
locking for the CMP. I am now getting this exception. Can someone on the
Jboss team tell me why this exception now shows up during a create()? I
know that I would be seeing a different exception if the bean with the
same PK already existed. This wasn't happening until I modified the
jboss.xml to have a custom container configuration.

The code in question:
workflowStorage =
(WorkflowStorage)home.create(workflowEntry.workflowIdentifier,
workflowEntry.workflow);
Where the create sig is:
public WorkflowStorage create(String workflowId, Object data)
throws CreateException, RemoteException;
