The zipfs enhancements that allow for storing POSIX permissions in zip archives via the zipfs file system provider of SapMachine11 have a compatibility issue with earlier SAP-closed versions of this.

The original closed version would restore an empty set of permissions as default return value of ZipFileAttributes::permissions while the initial version in SapMachine11 would throw an UnsupportedOperationException. The later needs to be changed to keep compatibility.
