DetachedHANamingService does not register its ObjectName with Registry. Because of this, if it is used with ProxyFactoryHA and JRMPInvokerHA, calls to it will fail in JRMPInvokerHA.invoke due to a failure lookup the ObjectName in the registry.

The purpose of having DetachedHANamingService as a distinct base class from HANamingService is to allow use with the detached invokers, so not having this work kind of defeats the point.
