Hi David,
The fix looks good to me. To answer your questions:
1. Using the XAWT macro is correct. It is only defined if we're building
the XToolkit, which we don't on the Mac. However, everywhere else we
actually check
#ifdef MACOSX
// ... do Mac stuff
#else
// ... do X11/Linux/Solaris/etc. stuff
#endif
We're unlikely to start supporting XToolkit/XAWT on Mac in the future,
so is there a reason not to use the MACOSX macro instead for consistency
with the rest of the code?
2. Regarding factoring out the X11 code: firstly we need to rename
src/solaris/ to src/_nix/ (where _nix could stand for UNIX and whatnot).
In that case, moving X11-specific code and OSX-specific code into their
corresponding directories would make sense. Obviously, this is a huge
project and I don't see this happening any time soon.

JBS issue:
https://bugs.openjdk.java.net/browse/JDK-8003900
Summary:
The X11 toolkit was disabled on the Mac but the dependency was not completely
removed for the release of 8.
This ended up being a lot simpler than I'd anticipated, but I have a couple
questions:
1> I've surrounded X dependent code with #ifdef XAWT blocks, I'm not entirely
sure if this is proper (it appears to be...)
2> I have thoughts that maybe the X11 dependent code should be factored out
into a X specific location rather than just disabled or worked around in the code.
The code seems pretty well ingrained, so this may be a larger task than necessary.
To validate the removal of the X11 dependency, I did the following:
Preparation:
- Copied /opt/X11 (installed by XQuartz) to somewhere I could readily modify,
let's call it ~/java/X11-good
- Made a second copy to ~/java/X11-bad
- Modified the header files in ~/java/X11-bad, adding #error statements to
cause compilation to abort if any are included
- Created a symlink to ~/java/X11-good at ~/java/X11
- Removed /opt/X11 and the /usr/X11 symlink, the latter is important as that's
one of the locations that configure searches
To validate building with no X11 headers or libs:
- Ran configure with no special arguments, it was not able to find X headers
- Ran "make jdk", ran SwingSet2.jar, everything was happy
To validate building *with* X11 headers and libs, but XAWT disabled (as it
should be on Mac):
- Ran "configure --x-includes=~/java/X11/include --x-libraries=~/java/X11/lib",
configure found X headers
- Ran "make clean-jdk jdk", ran SwingSet2.jar, everything was happy
To validate the above configuration does not actually USE X11:
- Changed the ~/java/X11 symlink to point to ~/java/X11-bad
- Ran "make clean-jdk jdk", ran SwingSet2.jar, everything was still happy

I submitted a JPRT run with this and the patch for 8042440 applied and there
were three failures, two in crypto tests (solaris/sparc9) and one on windows
due to a network issue (transient issue?). None of the failures were relevant
to AWT or Java2D or X11 in general. There were no build failures.
