Class ClassloaderSwitchingMBeanWrapper

java.lang.Object

javax.management.StandardMBean

org.mule.module.management.agent.ClassloaderSwitchingMBeanWrapper

All Implemented Interfaces:

DynamicMBean, MBeanRegistration

public class ClassloaderSwitchingMBeanWrapper
extends StandardMBean
implements MBeanRegistration

Ensures any external jmx invocation (like e.g. remote) is executed with a correct application classloader (otherwise a bootstrap classloader is used by default for platform mbean server). Note the irony - extends StandardMBean, but StandardMBean is not your 'standard mbean', but rather a special kind of the DynamicMBean which generates attributes/operations based on the passed in interface (via reflection).
