The clear glass has some issues with refraction not coming through without caustic cache, or bidir.
Just set the reflection to black and then you see the difference.

This looks a bit like a claming issue, are you using clamping?
Can you upload the scene so someone can have a look?

don`t use clamping in this scene

try to set reflection color to black.it does not help

the problem was in visibility properties panel
specular rays for area light was disabled for default

I guess you were using a daily build. Try the latest one, area lights should now again have specular ray visibility enabled by default.
