The operations error messages on the console seem to relate to the disabled operations. It looks at first glance that these operations are the ones with non-serializable parameters such as Fqn. The operations that take serializable parameters such as String are enabled and seem to work properly. Bottom line seems to be that mbean attributes and operations are only functional in a remote jconsole if they use serializable parameters and return values.
