Bump license year

The ErrorHandler's job includes handling out of memory (OOM) exceptions,
therefore it is imoprtant that that feature works. In the current state,
when handling OOM exceptions, the error handler produces an OOM error
itself, because the old 10k reserve is apparently not enough anymore.
To mitigate that, the reserved memory gets bumped to 32k (which is enouogh).
