- added an @AfterEach tearDown method - the testMultiLoadSimpleIdEntityPessimisticWriteLockSomeInL1CAndSomeInL2C was missing the enableSessionCheck(true) setting - removed the tests that use optimistic/optimistic_force_increment since these modes are only legal for versioned entities Signed-off-by: Jan Schatteman <jschatte@redhat.com>

Thanks, @jrenaat!
I have left some very minor suggestions.
But on the test side of things, I have this additional feedback:
- This bug also affects
Session.findMultiple()when passed a lock mode as aFindOption, so we should test that too, since that's what we now recommend. - If you look at my commits on this issue, the bug also affected load by natural id, so we should test that too.
- I know that this is harder to test, but we really should test that the lock mode is actually affecting the generated SQL.

Few minor comments, but the fix looks great!
Though not strictly necessary, it would be nice if you could also apply the correct code-style to the test class.
Edit: looks like @gavinking beat me to this, I agree it would be great to add more tests and perhaps the fixes could be similar.
