I typed this in weirdly and quickly so the output is a little different but I believe this is a bug in 1.7. JRuby 9k matches MRI in both 2.2 and 1.9.3:

system ~/work/snippets 1699% mri22 my_dir/test.rb 
OTHER HELP
system ~/work/snippets 1700% jruby my_dir/test.rb 
OTHER HELP
system ~/work/snippets 1701% mri19 my_dir/test.rb 
OTHER HELP
system ~/work/snippets 1702% ../jruby-1_7/bin/jruby my_dir/test.rb 
Heling in mydir

You're right, I just installed 1.9.3 and 2.2.2 and they both behave the same as Jruby 9000. Dang, I had gotten pretty used to this behavior... Thanks!

This is the same issue as #3092, fixed for 9k in 7e7292e. I'll apply the require_relative fix for this bug as well as the File.realdirpath fix.

This still needs a spec somewhere, but it has been fixed for 1.7.22.
