I get the same error with any graphical application too.

I think this may be a build problem with the openjdk7-bin package.

The exception is generated because the arrays of icon data in rt.jar
are zero length. The class files containing the icon data have been
automatically generated from .png files using a java app (in
ToBin.java) which renders them then extracts the raw data.

I haven't found a way to get ToBin to fail yet, it still works if
DISPLAY isn't set. Which JDK was used to build the binary package ?

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
