Hi all,


Please help review the changes for JDK-8199776 to JDK8u:-


Master Bug: https://bugs.openjdk.java.net/browse/JDK-8199776 

Webrev: http://cr.openjdk.java.net/~rpatil/8199776/webrev.00/



We have bug JDK-8197398 fixed in jdk 12 where Files.walkFileTree walk indefinitely while processing JAR file with "/" as a directory inside.

Since code for zipfs in jdk8dev different compared to jdk 12, the fix is not exactly same. 


Proposed fix:

While iterating over the zip entries added a check to see if entry name is equal to "/" (absolute path). If the entry name is equal to "/" we don't add it to "inodes" map.
