All Implemented Interfaces:
DefaultMBeanServerInterceptorMBean, MBeanServerInterceptor

public class ContextClassLoaderMBeanServerInterceptor
extends DefaultMBeanServerInterceptor

This interceptor sets the context class loader to the proper value for incoming calls. It saves the current context class loader, set the context class loader to be the MBean's class loader for the current call, and on return re-set the context class loader to the previous value
