Yes, the last email I found was:
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2009-August/007037.html
Kees hasn't posted a response yet.

I did however, find a very similar patch posted by Diego "Flameeyes" 
Petten for an older hotspot:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2007-May/000000.html

Diego is on the list at http://sca.java.net/CA_signatories.htm#p. 
Perhaps if I start from Diego's patch and update it to work with newer 
hotspot, upstream might accept it.

Thanks,
Omair
