> Key: OPENJPA-91
> URL: https://issues.apache.org/jira/browse/OPENJPA-91
> 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: Anders Monrad
> Priority: Minor
> 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;)
