Issue clearing ORM session when using similar objects in flush scenario

I Hav ethe current test case:

It basically creates a new user in the datbase, flushes to make sure it persists
Then using my abstraction method it deletes by ID, I flush to persist and then clear the session to make sure the object is removed from the hibernate session cache. Then I try to load it and check if it exists. If I run this test case in isolation, then I have no issues. However, If I run this alongside other test cases that are similar, code below. Then the expectation fails, the entity load does in deed return the deleted user object.My gut feeling is that the clear session is not removing the objects from session.

Here are companion tests:
