Carsten Ziegeler resolved FELIX-5328.
-------------------------------------
Resolution: Fixed
Thanks for the patch, [~kwin]. I've applied a slightly modified version which
leaves the call to process() in the try/catch block. I'm not 100% but I think
to remember that a CNFE can be thrown from there as well
