> I have entities User and Role  with a many-to-many association mapped with cascade="all". So merge and evict operations on User should be applied to this association. 
> When I do the following : 
> 1) create user u existing in DB
> 2) add a new Role r to this user (this Role don't exists in DB)
> 3) merge u 
> 4) evict the instance returned by the merge operation
> 5) use the same session for any operation
> 6) commit the session
> I get this exception : "org.hibernate.AssertionFailure: possible nonthreadsafe access to session".
> There is no thread issue. I think this is a standard way to use merge and evict operations.
> I think that merge and evict operations used on modified entities leave the session in an inconsistent state.
> See unit test wich reproduct this bug.
> Does a workaround exist for this bug?
