Kulla build broken on Mac

[Jan Lahoda]

Hi Ben,

I am personally not aware of any Kulla-specific changes in the hotspot 
repository. I see some classes were moved to different 
directories/packages in the hotspot repository. Was the build a clean 
build? If not, could you please try to do a clean build (e.g. "make 
clean; make images").

Thanks,
     Jan
