[infinispan-dev] All demos should be readily discoverable by RHQ

[Alan Santos]

RHQ scans the process list and looks for specific strings.  Some plugins then attach to a remote JVM and then look for specific means. 

If the selected port is spit out in a log it *could* be picked up after the initial process discovery.  

Right now it doesn't take advantage of JDK 6 tools or JMX enhancements that allow processes to attach directly.
