SUGGESTED FIX The following changes are under testing and review:- http://analemma.sfbay.sun.com/net/neeraja/export/ysr/coops/webrev/

EVALUATION This should be much, much simpler than extending compressed oops to CMS, which ###@###.### is currently working on. I am however targeting this to hs14 because it's not practical to expect this work to be ready before hs13 freezes in a month or so, with more important work needing to be done for hs13.
