33 * Managed objects are responsible for exposting attributes, operations and notifications. They will expose
34 * these outside the JVM therefore it is important not to use implementation objects directly as managed objects.
35 * Instead, creating inner classes and exposing those is an effective way of exposing internal state in a
36 * controlled way.

38 * Although we do not explictly use them while targetting Java 5, the enhanced MXBean approach in Java 6 will
39 * be the obvious choice for managed objects.
