This looks good.  Thanks for the update.

Minor comments below and you can make the change before you push (no need for a new webrev).

   key and msg should be final fields

  nameToVersion can simply be Map<String,Integer> (I missed this last round)

  63     public static void add(JarFile jarfile, JarEntry e, ClassFile cf) throws ConstantPoolException {

- can you break “throws …” to the next line.

  56                 String name = cf.getName().replace('/', '.');
  57                 nameToVersion.put(name, version);

Can you add a check to make sure the version is the same if the entry is present; otherwise, throw InternalError.  This will catch any unexpected code path.
