JMXMAPI

The other management API available in JRockit is JMXMAPI. JMXMAPI can be seen as a JMX-based version of JMAPI, even though there is not a one-to-one mapping between the two. JMXMAPI is currently not supported and is subject to change between releases, without notice.

The name space (domain) of the MBeans for JMXMAPI has changed with every major JRockit release. With R28, it was changed once again due to the Oracle acquisition. Even though it is highly unlikely that Oracle will be acquired, as we have the luxury of not yet supporting the API, expect it to continue to change for a while. The JMXMAPI MBeans were originally co-located with the java.lang.management MBeans (see Chapter 7) in R26.x, but were later relocated to the bea.jrockit.management domain and finally moved to the oracle.jrockit.management domain. The best version-independent way to access a certain feature of JMX is by using the RJMX proxy layer introduced at the end of the Management Console chapter.
