The JDBC3 persistence was an experimental addition that was never finished or properly tested.
http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigJBossMQJDBC3Persistence

Since JBossMQ is in maintenance mode pending JBoss Messaging and nobody wants to finish this work,
the source code and examples should be moved to the WIKI as an example persistence manager implementation
and removed from the production distribution.
