RFR+RFA [11u] 8197398: (zipfs) Files.walkFileTree walk indefinitelly while processing JAR file with "/" as a directory inside.

[Langer, Christoph]

Please review and approve the backport to 11u:



Original Bug: https://bugs.openjdk.java.net/browse/JDK-8197398

Original Fix: http://hg.openjdk.java.net/jdk/jdk/rev/2e4cf4ca074c

11u webrev: http://cr.openjdk.java.net/~clanger/webrevs/8197398.jdk11u/



The patch did not apply cleanly to 11u, because it conflicts with other changes that had already been done in ZipFileSystem.java.

Testing: jdk.zipfs jtreg regression tests ran successfully.


Thanks
Christoph
