Fix exception merging to be compatible with Java 1.6.
Don't access resources during shutdown.

The XaDataSourceManager was creating new resources in
unregisterDataSource(). When this method is called during shutdown,
other components may already have been shut down so the resource
creation may fail.

The particular case we saw was a race condition shutting down during a
master switch, which caused a NullPointerException in
XaConnectionHelperImpl when LuceneDataSource tried to create a
LuceneXaResource with a null XaResourceManager (which had been nulled
out during the master switch).
Remove a catch block that was suppressing failures in a test and make the test more robust.

The catch block in HTTPLoggingDocIT was suppressing all failures. Once
it had been removed it became apparent that the test was
flaky. Specifically it almost always failed in my IDE when run
alone (although it passed when run with the other tests in the file). I
believe the flakiness was because the log file wasn't always flushed to
disk before the assertion was reached.
Isolate HTTPLoggingDocIT from other tests that use the shared server.

o Server tests that create their own server need to extend
  ExclusiveServerTestBase in order to ensure that the shared server is
  not running while they execute.
o HTTPLoggingDocIT runs its own server because it needs specific
  configuration.
Server can dictate which logging kernel uses

And will, in the server setup, have server and kernel use the same logging mechanisms.
This commit also removes usages of java.util.logging from server in favor
of the console logger in kernel.

Don't swallow output in problematic test.

TestRecovery is failing on OSX under TeamCity. We need to avoid throwing
away the output from the subprocess so that we can diagnose the problem.

Revert "Specify Java subprocess is headless. Needed on OSX with Java 1.6 only."

Found a better way to do this. If we use MAVEN_OPTS to set the headless
property then it is inherited by subprocesses.

Fixes issue with client shutting down before transactions are pulled

The client the store copy method needs to perform full store copies over
 the network was closed by the RemoteStoreCopier before the transactions
 were pulled over in their entirety from the master. That can lead, in the
 presence of high transaction data volume, CCE to be thrown while doing
 full store backups. This commit fixes this issue by introducing an
 explicit done() method for the StoreCopyRequester that closes
 the client at an appropriate time.
RemoteStoreCopierTest is properly altered to check for the correct call
 sequence.
Removes some System.out.println calls that were added for monitoring
 purposes.

Produces NodePropertyUpdates given all changed property records for node

instead of doing so per changed property record. This needs to be like
this since properties (PropertyBlock) can move from one record to another
and should be interpreted as a change. The issue that caused this change
was that such a move produced one ADD and one REMOVE update and if they
got executed in the order of ADD then REMOVE the index would end up not
having that entry in it.
