I'm trying to run this query:

delete StoredMessagePendingClient m where m.clientId = :clientid and m.message.messageId = :messageid

This generates the following SQL, which fails under derby because derby doesn't accept two tables seperated by a comma (I'm anyway not trying to delete from both tables, only from the first one, so that SQL is wrong).

Hibernate: delete from MESSAGES_PENDINGCLIENT, MESSAGES storedmess1_ where CLIENT_ID=? and ID=?

WARN: SQL Error: 20000, SQLState: 42X01
Apr 05, 2015 5:32:05 PM org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions
ERROR: Syntax error: Encountered "," at line 1, column 35.

Also note the same query also fails under hsqldb for different reasons (going to create another issue for it) so it's REALLY annoying
