Restrictive file permissions: permissions removed also for owner on NTFS if Acl does not contain
explicit entry for owner
-------------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-5492
                 URL: https://issues.apache.org/jira/browse/DERBY-5492
             Project: Derby
          Issue Type: Bug
          Components: Store
    Affects Versions: 10.9.0.0
            Reporter: Dag H. Wanvik


It turns out that the file owner does not necessarily get an explicit AclEntry; this depends
on whether the created file has sufficient permissions already through, say, a permission
for everybody to write. The present logic removes all AclEntries except those granted to the
file's owner, erroneously presuming there would be such an entry always. This led to all AclEntries
being removed.
