Description

Once in a while two GeronimoServerBehaviourDelegates are created for the same IServer and GeronimoServerBehaviourDelegates.initialize() is called twice. Here's a call stack from the two calls to .initialize():

I believe the first call stack leads to ClassCircularityError since ConfigurationElementHandle attempts to load GeronimoServerBehaviourDelegate class which combined with lazy activated bundle forces the Activator to be called which attempts to load the GeronimoServerBehaviourDelegate class.

Disabling lazy loading seems to help.
