We had issues using jconsole remotely a while back (jdk 1.5.0_02) that we
were never able to solve.  If memory serves, jconsole opens a connection on
the specified port to that Java instance.  An additional port or two (I
can't remember) are then opened and the ports that are used are somewhat
random making it very difficult to do this through anything that needs to
port forward or needs ports opened.  I do not remember if the additional
ports are opened by jconsole or the other way, but you can see it by
connecting locally and checking netstat for connections to/from the jconsole
process.  The only solution here is to be able to specify the additional
ports, but at the time there was no way to do this.  I have not looked into
the jconsole or JMX options since so I do not know if this was added.
