Review comment:
With regard to test, we tried and it was somewhat tricky(we had to add jmx
configurations in system property and executed "artemis run" in a standalone
process).
By the way, previous artemis server exported the jmx this way. Although we
upgraded our server, we kept the original configs(including jmx configs) to
make the operations more efficient and less error-prone.
