I've never had much luck with the IBM JDKs. I'd recommend switching to
the official Sun version.

I have a variety of java implementations installed, and here are are
results for all of them. My archiecture is:
more /etc/lsb-release

All java versions below are the complete output of "java -version"
I've not differentiated between jre/jdk/toolchain, since I don't think
that compilation is an issue here (it's a hassle, I can if anyone
needs me to).

I have now tested my basic setup with Mac OSX, Windows and Ubuntu Linux.
Although it all works fine for me, Don still reported problems that we don't
understand.
So I would be very obliged if there are some other Linux users who would
like to give it a try. All you need to do is download a zip-file from this
location here:
https://plug-and-go.dev.java.net/files/documents/9557/115949/CGOS.zip
Unzip it, go to the CGOS directory that got extracted from the archive in a
terminal window and type:
java -jar GTPTester.jar "java -jar GoEngineGTP.jar"
literally, with the double-quotes. Better copy-paste the whole line. If
everything goes as planned, you'll see lots of move-coordinates whiz by and
in the end it should print "Your Go engine checked out OK!". I'd like to
know if there are Linux users who see something different.
Note: this assumes you have Java 1.5 or higher installed. This can be easily
checked by typing: java -version in the terminal.
Mark
