JRuby 9.2.0 shows `LoadError: no such file to load -- io/console/size`

[yahonda]

CI with jruby-head for actionpack has been failing at Travis https://travis-ci.org/rails/rails/jobs/356541503

Steps to reproduce

$ cd actionpack
$ bundle install
$ bundle exec ruby -Itest test/journey/routes_test.rb

I think this is not specific to routes_test.rb. It could reproduce almost every test.

Expected behavior

Tell us what should happen

Actual behavior

$ bundle exec ruby -Itest test/journey/routes_test.rb

GEM=am,amo,aj is also getting the same LoadError: no such file to load -- io/console/size https://travis-ci.org/rails/rails/jobs/356541504

cc @headius @enebo

[headius]

A new addition to the io/console library it seems?

[yahonda]

Doing git bisect and found #32160 requires "io/console/size"

[enebo]

@yahonda a more useful reference may be when ruby stdlib included it version-wise. The fact rails includes it is a big deal though.

[bogdanvlviv]

io/console/size was added in ruby/ruby@aef01ee

[y-yagi]

Workaround:
IO.console_size is wrapper for IO.console.winsize. Therefore, if can not use console_size, can avoid using console.winsize.
Ref: Workaround for JRuby console size.

Ahh it's just a pure-Ruby item. We are likely just not copying it from MRI. I'll get that fixed.

[headius]

This is now fixed on JRuby master.

Awesome folks ! Thanks for reporting @yahonda and thanks for the quick fix @headius !
