Well, the link seems broken (neither IE nor Netscape 
can display the page)

Anyway, the .class binary parser is quite OLD, and 
anyway it is very difficult to parse java classes (you 
can not 'patch' on-the-fly embedded URLs inside, 
because you'd have to rebuild the complete class file 
structure)

I will attempt to fix several problems related to 
codebase/base and other path problems in the future 
(this is on my huge todo list), but this won't fix ALL 
problems.
