The check to see if Hibernate Search exists on the class path is broken and yields this error:
13:45:34,796 DEBUG [HibernatePersistenceProvider] no Hibernate Search, sorry
This forum thread has more details:
I am seeing this with the 3.2.2.-SNAPSHOT release of Hibernate Search, but I think the 3.2.1.Final release has the same issue. Per the thread, the 3.3.0Beta1 release definitely has the issue.
