Hi,

Actually, I never used java3d for more than a few tests back then. I
tried it now, and it is working for me with jdk1.4.2:

-----8<------------
[klamath] /usr/ports/java/java3d/work/demo/java3d/HelloUniverse>JAVA_HOME=/usr/local/jdk1.4.2/ LD_LIBRARY_PATH=/usr/local/jdk1.4.2/jre/lib/i386/ /usr/local/jdk1.4.2/bin/java -cp /usr/local/jdk1.4.2/jre/lib/ext/j3dcore.jar:/usr/local/jdk1.4.2/jre/lib/ext/j3dutils.jar:/usr/local/jdk1.4.2/jre/lib/ext/vecmath.jar:. HelloUniverse

Java 3D: concurrent threadLimit = 1
[insert spinning cube here]
----------->8--------------

As you say you updated from 1.3.1 to 1.4.2, could you check whether 
/etc/libmap.conf contains correct references to the java3d libs in your
$JAVA_HOME/jre/lib directory? Are the files really there? It may be
necessary to recompile java3d with your 1.4.2 java, too.

HTH,
Andreas
