> The NPE is due to the following code: -
> {noformat}
> } else if (callback instanceof AvailableRealmsCallback) {
> Collection<String> names = stateRef.get().getMechanismConfiguration().getMechanismRealmNames();
> if (log.isTraceEnabled()) {
> log.tracef("Handling AvailableRealmsCallback: realms = [%s]", String.join(", ", names));
> }
> if (! names.isEmpty()) {
> ((AvailableRealmsCallback) callback).setRealmNames(names.toArray(new String[names.size()]));
> }
> handleOne(callbacks, idx + 1);
> {noformat}
> If mechanism configuration is mandatory this should report an appropriate error, if not it should fallback to specifying an empty list.
