Thus, it is hit or miss whether you can run any given "naked JVM" containing 292 with some proposed extract of 292 functionality from some rt.jar.

The bootstrap API is being simplified and 'invoke' is being renamed 'invokeExact' (and being joined by a fraternal twin, 'invokeGeneric').
I prefer to see invokeGeneric as a the dark side twin,
more powerful but without a clear performance guarantee :)
