> 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.
> This error is seen in Oracle's nightly regressions for Windows, but did not
> reproduced when running manually on Windows. This was due to different
> default inherited permissions on the directories in which the regression
> tests were run.
