But it could roll over (yes, I know unlikely), and you also have the issue of encoding the node that generates the long into the long which is open to corruption if nodes join/leave and the cluster size is large.

But it's no biggie, works for now basically.  Just keep in mind that in future a more robust/direct 1-to-1 mapping between XID and some JMX-friendly representation may be necessary.
