We would not want to couple the classlib to a particular VM however. So 
far I have been thinking
about the HDK from a classlib perspective, without considering the VM 
used. I imagined that any
developer who used a classlib HDK would just grab a VM snapshot (or the 
IBM VME) and overlay
that onto the classlib HDK in the same way we overlay the VME onto 
deploy now.

I suggested in the "Supporting working on a single module?" thread 
(sorry, no link - it's not in the
archives yet) that a Harmony VM could produce releases in a jre or jdk 
layout. This
would allow a Classlib developer to grab an HDK and overlay the VM jre 
bundle onto it,
but at the same time an actual Harmony runtime user could grab a 
classlib jdk/jre snapshot and
combine it with the same VM.
