I haven't tried it yet but will do, I have had a look at it. My guess
is that openjdk7-bin was built using a JDK that didn't have png
support, wip/openjdk won't have this problem as it rebuilds itself
after the initial cross-compile has finished.

I just rebuilt the icon files using openjdk7-bin and patched rt.jar,
the graphical demos work fine for me now.

I have put a tarball of the fixed class files onto ftp.n.o at:

ftp://ftp.netbsd.org/pub/NetBSD/misc/rjs/rt-patch.tar.bz2

To use it, untar it somewhere then run:

# jar uvf /usr/pkg/java/openjdk-bin/jre/lib/rt.jar sun/awt/X11/*.class
