[janvandeklok]

The session.flush() does not seem to make any difference!

Changed the code in class Join as follows:

 109       if (session!=null) {
  |  110         LockMode lockMode = LockMode.FORCE;
  |  111         if (parentLockMode!=null) {
  |  112           lockMode = LockMode.parse(parentLockMode);
  |  113         }
  |  114         log.debug("forcing version increment on parent token "+parentToken);
  | 115          session.flush();
  | 116          session.lock(parentToken, lockMode);
  |         }

and here is the stack trace:
