ISPN-2699 Fix compilation error in the Spring module
ISPN-2537 LockCleanupStateTransferTest fails randomly

LockCleanupStateTransferTest assumed that once the tx is done on one
remote node, it's done on all of them (and on the originator as well).
ISPN-2821 Correct Query Sort tests
ISPN-2792 Allow logging at TRACE level for a single test in the test suite

Add a log4j filter that allows TRACE messages only if the thread name
matches a regular expression.

Also add a shutdown hook to CompressedFileAppender to make it more likely
that the log file is properly terminated.
ISPN-2790 ReplCommandForwardingTest fails most of the time in CI

Looks like joining the cluster can take more than 3 seconds in CI, so I
increased the timeouts to 15 seconds.
ISPN-2832 upgrade to JGroups 3.3.0.Alpha2
ISPN-2584 BackupReceiver survives cache shutdown
- on each cache.stop() the backup cache is removed from the backup receiver repository
ISPN-2746 testDistributedPutWithTopologyChanges test randomly fails on all environments

The test wasn't properly waiting for the rebalance to end on the
servers before checking the topology id.
ISPN-2781 NPE in AbstractTopologyAwareEncoder1x

Copy the address cache into a regular map before generating the
topology response, to protect from changes from other threads.

Send "partial" topology responses even if not all CH members are
in the address cache. This allows the client to remove leaving
HotRod servers from its CH, even when one of the nodes doesn't
have a HotRod endpoint.
