> concurrent calls to move selector matching messages from one queue to another 
> or any wildcard type destructive JMX operation can break on concurrent 
> invocation.
> The move results in duplicates in the journal (waste of space) and incorrect 
> return counts due to inflight messages being visible in error.
> Two jmx consoles is enough to cause problems.
