/**
 * Verify that invoke method retrieves returned value of method from cache
 * or invoke operation depends on currencyTimeLimit > 0 and
 * lastUpdatedTimeStamp.
 * <ul>
 * Step by step:
 * <li>Create operation method without parameters which always returns
 * value.
 * <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 method thru invoke method of MBeanServer.
 * <li>Verify value which the invoke method returned is the same as value
 * which the operation method returned.
 * <li>Verify that operation method was invoked.
 * <li>Verify value of field `value` in descriptor for
 * ModelMBeanOperationInfo object.
 * <li>Invoke again operation method thru invoke method of MBeanServer.
 * <li>Verify returned value is not changed.
 * <li>Verify that operation method wasn't invoked.
 * <li>Verify value of field `value` in descriptor for
 * ModelMBeanOperationInfo object is not changed.
 * <li>Change returned value of operation method.
 * <li> Wait currencyTimeLimit seconds.
 * <li>Invoke again operation method thru invoke method of MBeanServer.
 * <li>Verify value which the invoke method returned is the same as value
 * which the operation method returned.
 * <li>Verify that operation method was invoked.
 * <li>Verify value of field `value` in descriptor for
 * ModelMBeanOperationInfo object is changed and verify this value.
 * </ul>
