My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with

Answer 1

If you happen to run your application inside Glassfish app server, simply run the following asadmin command, you would need to restart all running servers for the change to take affect.

./asadmin enable-secure-admin

There are extra Glassfish server configurations to further enable security, see more at Connecting remotely to Glassfish through JMX.
