Possibility of backporting fix for JDK-6986863

[Harald Kuhr]

Thanks Phil,

A backport would be great, and I really hope that happens!

Reading his (Sergey's) comments on my project issues, I was under the
impression that it would not happen, unless someone filed a bug/request for
this. But I will raise the issue again in the update mailing lists (if I
can find my way around them).


Again, thanks, and sorry for using the wrong list,
