I'm a bit skeptical to this fix.

First of all, I'd like to understand in what way make "bails out" if you 
have an extra directory with an Xcode project in it?

The code you are modifying is just the HotspotWrapper, which is a 
temporary solution for gluing together the old and the new build. It 
checks for modified files in the hotspot directory, to determine if the 
proper hotspot makefile should be called.

Is this code bailing out? How can that be? What is the error message?

Secondly, I think it is a good idea if we can get more support for IDE 
projects into the codebase itself. Unfortunately we have no really 
standard way of doing this. We have netbeans directories in top/common, 
jdk/make and langtools/make, and the hotspot Visual Studio project files 
are generated on-demant, and not checked in (if I remember correctly). 
I'm not entirely found of putting the ide project files in make, but at 
least we should be consistent. Just adding a new way, without addressing 
the old, is not helpful.
