[midPoint] v3.5 "500 Internal Server Error" on "Back" button.

Fri Feb 3 12:06:53 CET 2017

Hello Wojciech,

in the stack trace there's nothing that would give me any clue. And I 
don't see such exceptions when using 3.5. Please, could you create a 
simple "how-to reproduce" information, preferably on clean repository? 
And, if possible, please put it directly into jira. With fixVersion set 
to 3.5.1 & 3.6.
