Dan Berindei commented on ISPN-11465:
-------------------------------------

JGRP-2448 was also fixed in 4.2.0, and the uncaught exception appears as a failure in Jenkins, e.g.

{noformat}
org.infinispan.xsite.ImplicitBackupCacheStoppedTest[null, tx=false].Uncaught (from (empty))

> JGroups 4.2.1 includes a fix for JGRP-2435, which should fix the random failure in {{InitialClusterSizeTest}}.
> JGRP-2451 also adds a new failure detection protocol, {{FD3_ALL}}, which doesn't need extra heartbeats as long as the nodes are sending other broadcast messages.
