Class JMXSupport

java.lang.Object

org.jikesrvm.classloader.JMXSupport

All Implemented Interfaces:

Callbacks.ClassLoadedMonitor

public final class JMXSupport
extends Object
implements Callbacks.ClassLoadedMonitor

Implements functionality to support JMX classloading beans.

Pulling the functionality into the core of the VM will hopefully allow us to support multiple class libraries without having to duplicate a lot of code. TODO: we need to add OpenJDK support before we actually know whether that is true.
