I created a jira issue SHIRO-646
<https://issues.apache.org/jira/browse/SHIRO-646> as well as a pull request

The pull request contains a test and two fixes to make the test pass.

A small note to something I didn't check up on:
makes the error disappear. I can't invest more time in it right now, sorry.

I hope to check up on it in a few days if no one can explain it outright,
but trawling though all those classes has been a lengthy, albeit
interesting learning experience :)
