IIRC, there should be several new VM features now, namely the addition 
of the invokedynamic instruction and method-handles, as well as several 
new constant-pool entry types, ..., which were planned to be officially 
made available for the 1.7 release (unless something has changed, from 
what I read says they should be there).

they are mostly intended for aiding in the implementation of dynamic 
languages on the JVM.

I guess maybe by 1.8 there will be lambdas/closures.
