In other words, if JCP MR <x> does not require an RI, then it should not be surprising if there is no JDK build with maintenance version <x>.  As an example, JSR 337 MR 1 and MR 2 both used the same RI.  If this system property had existed during development of MR 1, it would return "1".  Since no RI was submitted for MR 2, a build returning "2" should never exist.  MR 3 did update the RI, so it would return "3".

I think that would be helpful, if not strictly necessary.
