Request for reviews (S): 6823453: DeoptimizeALot causes fastdebug server jvm to fail with assert(false,"unscheduable graph")

[Tom Rodriguez]

I think this:

+       Node* catchproj = proj_out(0)->unique_out()->as_Multi()- 
 >proj_out(0);

has to be coded more carefully.  That's the shape of a well-formed  
fall through edge but there's no guarantee it's well formed.  It's too  
bad the extract_call_projections logic isn't packaged up a little  
differently.
