Hi,
In ZipFileSystem.java, at 1071.
- The code will be more readable if you use character literal '/'
instead of 47.
- Save making an extra copy of the name array by testing for '/'
directly in the cen array
and create either the full name or the name without the '/'.
- 1073: The coding style should put the '{' on the same line as the 'if'.
Use the file's coding style.
Thanks, Roger

Subject: RFR: JDK-8197398 (zipfs) OutOfMemoryError when talking contents of
empty JAR file
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/
Background:-
The Files.walkFileTree walk indefinitely while processing JAR file with "/" as
a directory inside.
Proposed fix:
Files.walkFileTree api for jar internally uses ZipfileSystem. While iterating over the zip entries we have
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 so that we don't end up with infinite loop.
We have similar bug HYPERLINK
"https://bugs.openjdk.java.net/browse/JDK-8197398"JDK-8197398 fixed in jdk 12.
Below is the difference between fix for jdk 12 and jdk 8:-
The fix for above issue for jdk 12 handle a case where we can update an existing entry in jar with
"/" (absolute path). As in case of jdk 8 we cannot update the existing zipentry as doing
so we get "FileAlreadyExistsException". Therefore, fix for jdk 8u does not consider this
case.

Deepak
