The page http://common-lisp.net/project/armedbear/doc/abcl-user.html contains two pointers to files under this directory:
http://trac.common-lisp.net/armedbear/browser/trunk/abcl/examples/abcl/javac...
both are broken links. In fact, it seems that every example pointer to trac is broken. Once in the trac "not found" page, I have a 50% chance to get an Internal Server Error when clinking on Search, but last time, I got to a working page showing this last change:
(delete) @12718 [12719] 8 months mevenson Example reorganzation: delete 'abcl' directory.
It seems to indicate that the abcl directory under examples/ should be removed in the links, which indeed seems to be the case: I can reach this one instead:
