#2122

Problem occurs when the retry counter in the HiveServiceLocator is exceeded.
The retry counter is incremented on all exceptions and therefore is incremented on security exceptions (user/password wrong) as well.

Changed the caught exception to EndpointNotFoundException to avoid increment of the retry counter on wrong user/password.
