> Currently TokenBasedAuthentication.createToken() is synchronized and therefore serializes creation of tokens repository wide.
> Removing the synchronization shows test failures because the .tokens node is created concurrently by multiple sessions. Instead of serializing the calls, we could also use an optimistic approach. See attached patch. All tests pass.
