This is weird.  j2sdk-image/lib/tools.jar has the com.sun.mirror package,
but for some reason the jaxws build isn't finding it.

Is it a bug that java.home is being defined as j2sdk-image/jre rather
than just j2sdk-image?

I'm starting to suspect something in my build environment.  I'll try a
pure M5 build, without any Jigsaw changes, and see what happens.
