      Description

      java.lang.invoke use the pattern of a inner class Lazy to defer early initialization of some commonly used constants, which doesn't seem to actually be very lazy for a jigsaw Hello World.

      Moving to per-NamedFunction and -MethodHandle lazy initialization similar to the lazy initialization of Invokers.invokers defers substantial part of the startup overhead of the j.l.invoke infra hitting jigsaw runtimes.
