AFAICT this fix does not really change the existing implementation behaviour of URLClassLoader and URLClassPath. The patch redirects the processing of “jar:…/!” from the more general URLClassPath.Loader to the URLClassPath.JarLoader.

But i think the cracking of the URL within the jar URL can be made more robust. It probably should use

  file.indexOf(“!/“)

to check there is just one occurrence at the end.

Separately the spec of URLClassLoader could be clarified as to the current implementation behaviour.
