Alan, There are issues with java at the moment I think. The debian packages depend on default-jdk which corresponds to openjdk-6 at the moment. With this the java bindings and examples compile, but example 19 crashes. I think this is an issue with the way we handle 2d arrays between java and C but I've not tracked it down. I've not tried with gcj on debian testing / unstable - but it looks like I should try.
