I think it's a little more subtle than that, as I noted in my last comment on the --1.9 improvement request. When JRuby starts with --1.9 (whether through an arg, an opt, or a dotfile), it should essentially do:

ENV["JRUBY_OPTS"]="--1.9"

Of course, it should be a bit smarter than that, preserving other values, but this way you get the same expected behaviour that you get when MRI spawns another instance of MRI based on RbConfig::CONFIG["ruby_instance_name"].
