Basically we can not use sharp closure as a substitude when filter glossy is used. This is because we can not blur sharp reflection/refraction. This is quite quick and not really clean implementation. Not really happy with manual handling of original settings, but this is as good as we can do in the quick patch. It's a good acknowledgment and we now can re-consider some aspects of graph simplification to make such cases more natively supported. P.S. This failure would have been shown by our regression tests, so please, bother a bit to run Cycles's test sweep before doing such optimizations.
