> This changeset causes the URL returned from a ClassLoader.getResource(name) invocation to be reified, that is the URL is a direct pointer to either a versioned or unversioned entry in the jar file. The patch also assures that jar URL’s are always processed by the URLClassPath.JarLoader.  The MultiReleaseJarURLConnection test was enhanced to demonstrate that reified URLs are returned.  The SimpleHttpServer test helper class was moved into it’s own file.
I was happy to see John's note on diction so I assume the method will be 
renamed. Have you considered making it public so that tools and 
libraries outside of the JDK can use this?

One question on URLClassPath getLoader as it's not immediately obvious 
that this is needed. URLClassLoader specifies that any URL ending with 
"/" is assumed to be a directory.

Are you planning to update java.net.JarURLConnection as that has special 
handling for #runtime that will need to be replaced.
