Hi all,
This PR addresses the performance issue that is described in JDK-8287162.
With this fix, the ZipFileSystem methods: initOwner, initGroup, and initPermissions will not be invoked unless enablePosixFileAttributes=true.
Mach5 tiers1-3 are currently running and have not encountered any issues.
-------------
Commit messages:
- Only invoke initOwner, initGroup, and initPermissions when supportsPosix is true
