      Hi

      I have encountered something with I believe may be a bug in the jrt
      filesystem.

      The children/directory entries of
      /packages/com.oracle/java.xml.ws/com are
      /modules/java.xml.ws/com/sun
      /modules/java.xml.ws/com/oracle
      when I believe they should be:
      /packages/com.oracle/java.xml.ws/com/sun
      /packages/com.oracle/java.xml.ws/com/oracle

      You can use the following code to reproduce the issue:

      FileSystem fileSystem = FileSystems.getFileSystem(URI.create("jrt:/"));
      Path parent = fileSystem.getPath("/packages/com.oracle/java.xml.ws/com");
      try (DirectoryStream<Path> directoryStream =
      Files.newDirectoryStream(parent)) {
         for (Path each : directoryStream) {
           System.out.println(" parent: " + parent + " child: " + each + "
      startsWith: " + each.startsWith(parent));
         }
      }

      The output I get is:

        parent: /packages/com.oracle/java.xml.ws/com child:
      /modules/java.xml.ws/com/oracle startsWith: false

        parent: /packages/com.oracle/java.xml.ws/com child:
      /modules/java.xml.ws/com/sun startsWith: false

      This is based on b86 with Jigsaw on Mac OS.

      Cheers
      Philippe
