Hmm, that is interesting - FLUSH should not be necessary since we  
don't use it for anything.  If the startup does get stuck because  
FLUSH is missing then that is a bug.

Could you:

1.  Verify that leaving FLUSH out causes startup to get stuck, and  
adding FLUSH back in fixes it?
2.  Add a sanity check at the end of buildChannel() in  
JGroupsTransport [1] to ensure FLUSH is there otherwise throw a  
ConfigurationException
3.  Create a JIRA to investigate why FLUSH is needed!  It shouldn't be  
needed, could be some old JBC code in there (perhaps a flush gate)  
that is causing the problem.

Cheers
