I think there is a lot of stuff in j.u.concurrent that Derby could use, 
if only we could get a 1.5 version going ;-)

With the 1.1 J2ME profiles that support the 1.4 APIs now in PFD perhaps 
we should look at the platform roadmap going forward. Perhaps a split 
would be appropriate between a platform for embedded devices (based on 
CDC 1.1 and JSR-169) with little concurrent access and limited resources 
and multi-user standalone/J2EE servers (based on 1.5) optimized for high 
concurrent access with unconstrained resources.
