             Summary: TP: enable loopback by default and discard own multicasts
                 Key: JGRP-1765
                 URL: https://issues.jboss.org/browse/JGRP-1765
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 3.5


Enable {{TP.looback}} by default (deprecate and ignore prop): all messages sent by self are passed right to a thread pool to send them up again.

When a multicast message sent by self is received, it is currently passed to a thread pool, de-serialized and only then discarded if loopback=true. This means that we create an unneeded buffer for de-serializationand perform de-serialization.

SOLUTION: discard the multicast from self immediately when receiving it, in {{TP.receive()}}
