My thanks to Mark for raising this.  Blobs of unknown JAR code have
been a problem in the past for including OpenJDK in the GNU/Linux
distributions, and it would be a shame to take a backwards step on
These ones do just appear to be, so
providing some way to point to the JAR files instead should be
sufficient.  awt16.jar can be dumped, given OpenJDK (AFAIR) is
supposed to be built with a 1.6 JDK.

On the positive side, the patch applies to OpenJDK6 with a few simple
modifications, and by copying across the JAR files manually to
make/tools/swing-nimbus/libs, I was able to build with the following

So anyone wanting to try Nimbus on OpenJDK6 today, feel free :)
