JMX code is self contained in the j2se workspace: it has no dependency on other code in the workspace. Also, it is platform independent as it's only java code.

Thus, it is quite straightforward to provide a simple mechanism to build JMX classes.

However JMX code is contained in different source trees (/javax/management and com/sun/jmx) and needs generation of RMI/JRMP and RMI/IIOP stubs.

The provided mechanism would embed this knowledge to make building JMX code straighforward.
