Question about BUILD_HEADLESS and HEADLESS

The stub library is headless/libmawt.so*. Right? It's being built on Mac
OS as well, but currently being
put in a different location to the normal one. It also seems like it is
not being used
because if you rename or delete it, there isn't any change in behavior,
which sounds like a bug.
So, what exactly is the function of the stub library? Is it to allow
some functions of awt to work
that don't require a real display?
In any case, I don't see why Mac should be different from Solaris or
Linux in this respect.
* In 8 it has a different name, but it'll be built on Mac as well in 8.
