No, I mean that GCJ allows access package-private stuff (not only
classes) in other packages in Java code. Jikes doesnt allow this.

Thanks for doing this. I fiddled around with this several times already
when I tried to merge our code into GNU classpath.
Also Ranjit solved this issue by a bad hack (it was never accepted) some
time ago. http://gcc.gnu.org/ml/java-patches/2003-q3/msg00318.html
(sorry, I cant find the original mail from Ranjit in the webinterface
