[eclipselink-users] NullPointerException during commit

[David Parker <dap@xxxxxxxxxxxxxxxxxxxx>]

Every once in a while in our testing we get the following stack  
(eclipselink 1.0.2)

javax.persistence.RollbackException: java.lang.NullPointerException at  
org 
.eclipse 
.persistence 
.internal 
.jpa 
.transaction 
.EntityTransactionImpl.commitInternal(EntityTransactionImpl.java:102)  
at  
org 
.eclipse 
.persistence 
.internal 
.jpa 
.transaction.EntityTransactionImpl.commit(EntityTransactionImpl.java: 
63) at
....

Looking at the source code, I don't really see what could be null,  
but... I don't have the source code set up so that I can run under a  
debugger (Netbeans).

This only happens every once in a while. We only have one application  
thread. Has anybody run into this?

Thanks.
