Well there weren't any objections:

http://mail.openjdk.java.net/pipermail/hotspot-dev/2011-March/003992.html

Does the patch apply cleanly to both hs19 and hs20?

Now we have a bug ID, please use that in the patch name and place it in
patches/openjdk.  It's just a matter of time until they get it in upstream
AFAICS.

Please post a fresh patch with the extended fix posted upstream, having
made sure it works with both hs19 and hs20.

If you also want this in 1.10, you'll need to post a patch for that branch
too.  Note that the defaults are inverted there (hs19 is default, hs20
is optional) but they are the same versions.

I'll handle IcedTea7 when the patch is pushed to the 7 trees.

Thanks,
