Log files full of NonexistentConversationException
It looks like there are bots out there which have previously indexed Zanata pages (especially /error/) with cid parameters (from Seam's conversation scope). When Zanata 3.9 sees these requests, Weld tries to interpret the cid parameter as a CDI conversation, even though we don't use CDI's conversation scope. As a result, we get a lot of useless logging like this:
We should install a custom exception handler for NonexistentConversationException, and probably avoid logging them at all, or perhaps log them as DEBUG without the stack trace.
