 * Verify that invoke method invokes correctly method with parameter and

 * <li>Create operation method with name as in 1 step with parameter which
 * always returns the parameter.
 * <li>Create 2 ModelMBeanOperationInfo object for both operation method.
 * <li>Create ModelMBeanInfoSupport object with default descriptor. All

 * <li>Create ObjectName object.
 * <li>Register RequiredModelMBean object in MBeanServer with above
 * ObjectName.
 * <li>Invoke 1st operation method thru invoke method of MBeanServer:
 * server.invoke(objectName, methodName, null, null).
 * <li>Verify value which the invoke method returned is the same as value
