From 22e724e8292315f600b57a30716e26c1f1c04f66 Mon Sep 17 00:00:00 2001 From: Lukas Reschke Date: Wed, 30 Sep 2015 13:32:20 +0200 Subject: Only intercept exceptions of type "NotFoundException" instead of any Exception The sharing backend may throw another exception for example when the activity app encounters a problem. Previously this just triggered a 404 error page and the exception got not logged at all. With this change such exceptions get not intercepted and regularly handled as exceptions so that we have meaningful log data. Also the user will be shown a window informing him that an error happened.
