Deployment ERROR - EJB already exists!!!

[claudia.pt]

Hello!
I'm allways getting this error:
[MainDeployer] Could not initialise deployment: Error in accessing application metadata: ; - nested throwable: (javax.management.InstanceAlreadyExistsException:

Is it true that this is a JBoss4.0.2 bug?

What should I do?
Is it better use other version of JBoss?

Thankx,
Cláudia
