Looks like gij-4.0 fails to load awt/gtk completly... 

gij-4.0, libgcj6, libgcj6-awt and libgcj6-common installed,
all at version 4.0-0pre5

I was eventually able to get java applets working in konqueror using
only free software (!!) by commenting the following code from 
org/kde/kjas/server/KJASAppletStub.java

/* if (Main.java_version > 1.399)
      frame.setUndecorated(true); */

java_version, on the other hand is derived from the java.version
system property, looking at what gets reported:

java Main
JVM version = 1.4
gij-wrapper-3.4 Main
JVM version = 3.4.4
gij-wrapper-4.0 Main
JVM version = 1.4.2

Maybe that should be user configurable.

Looking at gcc java pages, apparently a big awt merge in gcc 
mainline, so perhaps these issues are already moot.
