Why don't we dump the JkMX and just settle for the facilities provided by 
Java 5 configurable via standard system properties: alone for local JVM monioring

for remote machine monitoring.

I checked both myself with jconsole shipped with Java 5. It works like a 
charm (apart from increased CPU Load on the machine the jconsole runs).
MC4J 1.2 B5 has no problems with attaching to remote JVM either, hovewer it 
has some issues with mbeans provided by JVM, MC4J folks are aware of.

The bottomline is: consider dumping o.a.jk.c.JkMX (I know, I know there is 
number of users wishing to run tomcat on JVM <1.5)
