When registering a bypass filter of class URIStartsWithVoter causes the server
to die
-------------------------------------------------------------------------------------
Key: MAGNOLIA-2085
URL: http://jira.magnolia.info/browse/MAGNOLIA-2085
Project: Magnolia
Issue Type: Bug
Components: core
Affects Versions: 3.5.4
Reporter: Ryan Gardner
Assignee: Philipp Bracher
Priority: Critical
All I did was follow the instructions on the wiki exactly as they are
written... After I created the nodeData for the class of the bypass filter -
and before I could put any more information in it - the server died with this
message:

I couldn't do anything to get it back at that point, and had to restore the app
from a backup.
It was as if the filter was being immediately put into effect, before it was
even configured fully. Even if it were configured completely wrong, there is
really no excuse for the server to completely die because of a bad user input.
