You may have discovered a bug. As far as I can tell, jboss incorrectly filters out
custom finder methods that don't begin with "ejbFindBy". Your method is filtered out.
An attempt is made to autogenerate a finder, which results in the indicated message.
Change the name of your method to ejbFindByIdAndName and try again. If that works, let
me know and I'll submit a patch.
