      Manually set the TCCL before invoking the method.

      finally

      Unknown macro: { // reset the TCCL Thread.currentThread().setContextClassLoader(previous); }

      TCCL not set to application classloader when MBean Notification is invoked
      If an application registers an MBean notification and it receives a notification, the Thread Context ClassLoader is not set to the application, this causes ClassNotFound exceptions on classes that are in the application's classpath.
