Exception handling in receivers and listeners

Hi again

In RequestHandler, Receiver, MessageListener or MembershipListener 
methods which are invoked by JGroups when some event has occurred, if an 
exception is thrown in the handler code, is it proper practice to catch 
the exceptions and deal with them locally (log them?).

Or is it permissible to wrap them in a RuntimeException and propagate it 
back into JGroups - if this happens - what does JGroups do with the 
exception - log it, ignore it or pass it back to the caller? (I guess 
passing back to the caller would only make sense for synchronous 
invocations made using messsage dispatcher)
