"Converge [the] best features of HotSpot and JRockit" - what does this mean for OpenJDK?

[David Herron]

In Theory ...

Theoretically JRockit could be changed to implement the same interfaces
HotSpot implements so that JRocket could plug into the OpenJDK runtime.
 That would allow any VM to plug into the OpenJDK runtime.  This was the
goal of the Clean VM Interface project (
http://openjdk.java.net/projects/cvmi/)

Right?
