There are very specific rules related to the use of the javax namespace.

I'm not sure exactly where this API would need to go. IIUC jcmd doesn't 
exist at the Java level it is just a tool, so introducing an API to 
interact with it seems problematic to me. Other folk in serviceability 
(both VM and JDK sides) will need to weigh in here.
