I finally got java to build with gtk support, but every program that I try to run fails like this simple example from a java book (pango is finding a null pointer) -

[dranta:java/CHAPCODE/Ch12] dir% gcj -bind_at_load --main=Application -o Application Application.java
[dranta:java/CHAPCODE/Ch12] dir% Application
