[Bug] zipfs unintentionally ignores umask/permissions

[Volker Simonis]

Hi Michael,

have you had a look at the recently added enhancements for zipfs:

8213031: (zipfs) Add support for POSIX file permissions
https://bugs.openjdk.java.net/browse/JDK-8213031

The corresponding CSR

8213082: (zipfs) Add support for POSIX file permissions
https://bugs.openjdk.java.net/browse/JDK-8213082

is also interesting to read as it discusses some of the long-standing
problems of the zipfs implementation which may be surprising for the
normal user.

Regards,
Volker
