Possible jrt filesystem bug

[Philippe Marschall]

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
