I never used WL, but I guess Roland says that for versions < 9.0, you're stuck.

WL < 9.0 have or use a JMX implementation of the 1.0 version of the
JMX specification.
MX4J never implemented that version, but went directly to implementing
version 1.1 of the JMX specification.
MX4J 3.0.1 implements version 1.2.1 of the JMX specification.
