Thanks for the tips, I wasn't using UrlSet at yet, but that looks
great . I am using ASM 3 with it, I don't know about new features you
could take advantage of, but it is easy to get it running. I think
this method is wrong on ClassInfo:
public String getPackageName(){
return name.substring(name.lastIndexOf(".")+1, name.length());
}
