Goodness, Lew! No, my statement is founded on the very same
understanding as yours. It just happens to be wrong (the statement).
Could you please stop exposing my mistake in such punctilious a manner? :)

I vaguely seemed to remember some kind of native call or the like
further down the call to #getEnumConstants. Hence the reference to the
VM. I cannot tell where I got that from, and should have challenged that
assumption. Yes, #getEnumConstants is a method that uses reflection to
achieve its function. Can I crawl back under my rock now?

I apologize.  I'm not trying to expose a mistake.  I really thought there was 
something there for me to learn.  I'm truly sorry.

You've been here long enough to know I've made much more foolish mistakes than 
yours.
