Hi Martin, thanks for the explanation.
After some further research we identified the reason for the problem. Shiro 1.3.2 has a bug, explained here: https://issues.apache.org/jira/browse/SHIRO-637. In case, there is no session any more, Shiro calls to getSession(false) returned a cached Session instead of returning null. This problem is fixed with 1.4. We will update Shiro to fix this problem. Thanks for your help.
