Darn. Compiling a small test program to bytecode goes ok:
gcj --classpath=/usr/share/java/jogl.jar -C Test.java
But when I try to run it, I get:
[john at localhost ~/dev/java/JOGL_Example]$ gij -cp /usr/share/java/jogl.jar Test

Compiling to object works also:
gcj --classpath=/usr/share/java/jogl.jar -c Test.java
but trying to link that fails:
