JEChangelogDB.java:
In CrossReplicaDBCursor.getCursorFrom(), let the ChangelogException go up.
Made sure calls to TRACER.debugCaught() are done where an exception stacktrace would be lost otherwise.

ReplicationServerDomain.java, ReplicationDomainDB.java:
Let the ChangelogException go up.

ReplicationBackend.java:
In writeChangesAfterCSN(), slightly changed the code because of ChangelogException going up.

ReplicationBroker.java:
debugInfo() should have been called instead of directly calling TRACER.debugInfo().
