Keith Johnston commented on JBAS-6821:
--------------------------------------
Just to clarify:
1. This stack trace occurs as a result of a naming collision between two mbeans used to manage the persistence units.
2. The persistence units themselves are still located independently in JNDI.
3. Each application will still get the correct persistence unit.
4. The error can essentially be ignored.

> Key: JBAS-6821
> URL: https://jira.jboss.org/jira/browse/JBAS-6821
> Project: JBoss Application Server
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: Deployers, EJB3
> Affects Versions: JBossAS-5.0.1.GA
> Environment: Win XP
> Sun JDK6 32 bit
> Reporter: Keith Johnston
> Assignee: Carlo de Wolf
>
> = Steps to reproduce =
> 1. Create a jar containing a META-INF/persistence.xml file.
> 2. Set the persistence-unit at name attribute to 'test'.
> 3. Wrap the jar inside an ear archive -> 'foo.ear'
> 4. Deploy the ear to jBoss -> works ok.
> 5. Rename the ear to 'bar.ear'
> 6. Deploy to jBoss -> javax.management.InstanceAlreadyExistsException is thrown, stack trace follows:
> 16:29:05,285 WARN [AbstractDeploymentContext] Unable to register deployment mbean org.jboss.metadata.jpa.spec.PersistenceUnitMetaData.test
> javax.management.InstanceAlreadyExistsException: jboss.deployment:id="org.jboss.metadata.jpa.spec.PersistenceUnitMetaData.test",type=Component already registered.
