Then you have a 1-to-1 mapping between the XID and a JMX-friendly String. :-) Or maybe
an SHA1 hash of the byte[].
yes,that would work as well. A long is smaller and (not that matters a lot) cheaper to
generate.
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.
