Hi Kevin, thanks a lot for your answer and for providing some useful links. Unfortunately I could not find anything related to our problem in the documented inconsistencies and issues. In the meanwhile I created a little test project on GitHub <https://github.com/mwalter/test-openjparelations> which shows the problems I mentioned above. Maybe you find some time to have a look at.
The JUnit test cases are green for OpenJPA 1.2.2 but as soon as you switch to OpenJPA 2.2.1 (by editing the pom.xml) test results change. Well, maybe I should have written the asserts to show green using OpenJPA 2.2.1 instead. In our opinion OpenJPA 2.2.1 behaves correctly regarding version incrementation when performing list operations like adding or removing. -- View this message in context: http://openjpa.208410.n2.nabble.com/Different-version-incrementation-behavior-or-bug-tp7582703p7582847.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
