Ah, right. This is about readdir64_r().

This is Bug 8207340: (fs) UnixNativeDispatcher close and readdir usages should be fixed.
It has not been backported to 8u, and as far as I can see there is no proposal that it
should be, either by OpenJDK or Oracle.

I don't know why this one didn't get backported. The patch looks quite straightforward.
There may be some issues with old operating systems that affect this, but given that
HotSpot is using the new readdir() I doubt that this would hurt. We are very cautious
when backporting to 8, which is rather elderly.

We could just put this patch in our queue, but it might help if you tried applying it
and got back to us.
