             Project: OpenJPA
          Issue Type: Bug
         Environment: Using OpenJPA (openjpa-all-0.9.6-incubating.jar) in Rational Developer 7 ( Websphere 6.1 test environment ) connected to Oracle 9.2 database.
OS: WinXP SP2
            Reporter: david zhang

             Fix For: 0.9.8


Hi ..

Not sure if this is a bug or just the way websphere reacts to openjpa. 

I have a small test program using OpenJPA against an Oracle database. I am running this program in the Websphere 6.1 test environment included with Rational Developer 7. This is all working just fine. But when I make changes to some ressource in the application, the chagnes are automatically published to the test environment and the app is restarted. After this I get the Exception below, whenever I try to access an EntityManager. 

If I restart the entire server, the app is running fine again. So I guess this is related to restarting the application.

Caused by: java.lang.VerifyError: class loading constraint violated (class: org/apache/openjpa/kernel/BrokerImpl method: newQueryImpl(Ljava/lang/String;Lorg/apache/openjpa/kernel/StoreQuery;)Lorg/apache/openjpa/kernel/QueryImpl;) at pc: 0
