[Yanel-dev] Strange NullPointer

[basZero]

maybe a hint:
where does the "identity" come from? how is it built?
because:
- at 3pm today i logged in with user A to our test system (cookies have been
set in browser)
- later I deployed a new version, from then on, the user A does not exist
anymore in the new version (this is on purpose).
- When I access the test system, the cookie is sent of course (containing
the username A which does not exist anymore). Somehow, the system throws the
NullPointer.

My opinion is: the NullPointer should not be thrown, because the following
"more legal" use case could happen easily:

1. user A registers and logs in
2. a sysadmin deletes for any reason user A
3. user A comes back to the site.... boooom.

Cheers
Balz
