Marcel Reutegger commented on JCR-1224:
---------------------------------------
Each JUnit test keeps references to JCR items, which are not set to null when
the test is teared down. We already had a similar issue: JCR-1224. Back then we
reduced the memory which is kept if the session is logged out but the session
instance is still referenced. It seems this not sufficient. I think it's time
to change the test cases.
