Ok, I removed that fix from my patch.

I think so too.

I removed the NO_EXCLUDES statement from Hotspot. This does not have any 
effect as long as no ProblemList.txt is present (in fact, had I thought 
a bit more on this before, I would not even have needed to add that 
guard for hotspot), but will facilitate merging with Igor's patch.

I discovered a few other issues in the Hotspot file (it turned out I 
didn't run the hotspot tests before with my jprt command :() which I 
also have fixed.
