Because Window L&F is only "allowed" to work on
a WinOS machine.  MS hasn't given JavaSoft permission
to allow its use on any other platform -- or so that's
my understanding of it.  Hence, the default look is
Metal.

I don't know the exact reason for this.  What version of MRJ are
you using?  Also, you might want to subscribe to the MRJ-Dev listserve
in order to ask you questions to a very knowledgeable group, including
MRJ engineers.
