This is just the ground work for what Valhalla and Panama are 
going to deliver, so eventually the JVM boilerplate will be 
hidden behind language features, just like it happens today when 
lambdas get actually converted into instances of invokedynamic 
calls.

Eventually those 25 year old jars will be able to run unmodified 
in a JVM that also understands value semantics, specialized 
generics and can do manual memory management within safe 
constraints.
