// Since our RequiredModelMBean implementation doesn't support
// persistence, it doesn't have any behaviour for OnUnregister, so we
// can't test that.  We can only test that the value is allowed.

// In versions of the API prior to the addition of OnUnregister,  the
// attempt to construct a DescriptorSupport with persistPolicy=OnUnregister
// will throw an exception.

// The OnUnregister value is not case-sensitive, and we test that.
