----------------------------------------------------------------

There is only the test instance in the cluster, no other members.
The same is observed using CENTRAL_LOCK2 instead of CENTRAL_LOCK.

When running the loop2 with tryLock(1000, TimeUnit.MILLISECONDS), the Loop stalls at random intervals for a second, tryLock returning false and then it recovers with:

14:28:55.220 [jgroups-3,test,test] ERROR org.jgroups.protocols.CENTRAL_LOCK2 - JGRP000124: discarded LOCK-GRANTED response with lock-id=1118, my lock-id=1119
