It probably should be located with URLClassPath but we should try to 
avoid exporting jdk.internal.loader to other modules. I suspect the 
module-info.java in your webrev is based on a merge and exporting this 
package to java.rmi seems dubious. Can we create a bug to get this 
removed? It looks like RegistryImpl is using it out of convenience 
rather than necessity.

There's something fishy with InvalidJarIndexException. The JAR spec 
mentions it but it's a JDK-specific exception. If it's thrown by the 
APIs in java.util.jar then it should be specified in those APIs and the 
exception needs to be java.util.jar.
