The bug is really funny. I tried some workarounds and found out that if I wanna load something like that:
SELECT w FROM Waffe w WHERE w.id IN (:waffenIdListe) waffenIdListe = List(Integer) the same error occurs. I just wanna load 2 Waffe Objects with their IDs = no chance. -- View this message in context: http://openjpa.208410.n2.nabble.com/WAS7-persistence-provider-problems-openJPA-Hibernate-tp5514291p5518088.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
