Yes, I strongly recommend to move to MX4J 3.0.x.
Maybe a dumb question, but the MBean does implement
NotificationBroadcaster ? That exception only happens if it does not,
or if there are ClassLoader problems.

To run MX4J on JDK5 on the server, did you set the system property
javax.management.builder.initial, and use MX4J's JSR 160
implementation via specifying a property in the environment Map of the
JMXConnectorServer ?
