Customer has both an LDAP registry and utilizing the
BasicRegistry. A  java.util.regex.PatternSyntaxException occurs
when searching using a  principal name in the form of
realm\username. This RuntimeException is uncaught in Federated
Repositories causing select UserRegistry calls to fail. This
will occur even if the configuration is set to allow operations
if repositories are down.

For the example above, the following failures may be seen:
