/**
 * Verify that invoke method throws exception if target operation method
 * throws exception.
 * <ul>
 * Step by step:
 * <li>Create operation method with one string parameter which always
 * throws an exception with message=parameter of this method.
 * <li>Create ModelMBeanOperationInfo object for operation method.
 * <li>Set value currencyTimeLimit = 0 in descriptor for
 * ModelMBeanOperationInfo object.
 * <li>Create ModelMBeanInfoSupport object with default descriptor. All
 * ModelMBeanXXXInfo except ModelMBeanOperationInfo are default.
 * <li>Instance of class created in 1st step sets managed resource for
 * RequiredModelMBean using setManagedResource method.
 * <li>Create ObjectName object.
 * <li>Register RequiredModelMBean object in MBeanServer with above
 * ObjectName.
 * <li>Invoke operation methodThrowException method thru invoke method of
 * MBeanServer with specific msg.
 * <li>Verify that MBeanException was thrown with nested exception which
 * has message which specified in previous step.
 * </ul>
