SimpleResourceAdapterRepository compares a given ResourceAdapter class with resource adapters from MetadataRepository just by their class names. So if there are 2 separate RAs deployed in the server both with the same ResourceAdapter class (e.g. org.hornetq.ra.HornetQResourceAdapter), it randomly takes one of those and cannot safely distinguish them.

3 places affected by this:
1. #getMessageListeners() [1]
2. #getEnpoint() because of usage of getMDRIdentifier [2] [3]
3. #getResourceAdapters() [4]

I used a dirty hack to work around this issue which changes API and doesn't fix #3, see [5] + a few changes according to [5] in WF's EJBUtilities.
A possible fix could be to "encode" the RA name into its uniqueId, so that such a uniqueId would contain RA class name, RA name and eventually a counter (increasing number).
