Two GeronimoServerBehaviourDelegates created for one IServer
------------------------------------------------------------
Key: GERONIMODEVTOOLS-760
URL: https://issues.apache.org/jira/browse/GERONIMODEVTOOLS-760
Project: Geronimo-Devtools
Issue Type: Bug
Components: eclipse-plugin
Affects Versions: 3.0
Reporter: Jarek Gawor
Assignee: Jarek Gawor
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.
