Yes, David Bateman has done it.

I don't use Linux, so it's difficult for me to give a complete description.
However, I can try to give some hints:
- JHandles has only been tested with Sun JDK, so it's better to use it; from
David's experience, the recommended version is 1.6
- David didn't use the pre-compiled packages of JOGL, but recompiled it
from source (this requires a few additional packages, but avoids any
library incompatibility). The jar files have been installed somewhere in
PATH (for instance /usr/bin) and the libraries have been installed somewhere
in LD_LIBRARY_PATH.
- When compiling Java or JHandles packages, you should pre-define
JAVA_HOME to the actual location of Sun JVM library: if the client JVM
is installed in /my/java/dir/jre/lib/i386/client/libjvm.so (replace i386 with
your actual architecture), then define JAVA_HOME to /my/java/dir
- When compiling Java or JHandles packages, be sure that "java" and
"javac" corresponds to Sun JDK; it happened to a few people that the
eclipse java compiler was used instead.

Hope this helps.

Michael.
