Feature Request: Install recent JRuby on Ruby VM

Background

I'd like to run a recent JRuby release against Rails 5 but per https://docs.travis-ci.com/user/languages/ruby/#Supported-Ruby-Versions-and-RVM only the 1.7 series is pre-installed in the VM. (Even the precompiled binaries still need to be downloaded and installed: http://rubies.travis-ci.org/ubuntu/12.04/x86_64/jruby-9.0.4.0 )

I'd make a PR to help if I knew where to make it and what was required. e.g, jruby-9000 still resolves to the jruby-9.0.0.0.pre1 release.

Build Examples

I see that ls /home/travis/.rvm/gems has

cache   ruby-1.8.7-head   ruby-2.1.2@global
jruby-1.7.19-d18   ruby-1.8.7-head@global  ruby-2.1.3
jruby-1.7.19-d18@global    ruby-1.8.7-p374   ruby-2.1.3@global
jruby-1.7.19-d19   ruby-1.8.7-p374@global  ruby-2.1.4
jruby-1.7.19-d19@global    ruby-1.9.2-p330   ruby-2.1.4@global
jruby-9.0.0.0.pre1   ruby-1.9.2-p330@global  ruby-2.1.5
jruby-9.0.0.0.pre1@global  ruby-1.9.3-p551   ruby-2.1.5@global
jruby-9.0.4.0   ruby-1.9.3-p551@global  ruby-2.2.0
jruby-9.0.4.0@global   ruby-2.0.0-p598   ruby-2.2.0@global
ree-1.8.7-2012.02   ruby-2.0.0-p598@global
ree-1.8.7-2012.02@global   ruby-2.1.2

but I'm not sure the relationship between gemsets being present and the binary being available on the VM.

It appears 9.0.5.0 is now available from the travis precompiled rubies but they are not used. ref: rails/rails#23499 (comment)

@bf4 Where's the build that shows it's not used? Seems that the Rails PR has had some forced pushes that hides things.

[bf4]

@BanzaiMan this is true re: force pushes.. I'm just trying stuff. Here's one https://travis-ci.org/rails/rails/jobs/114197771

And my rvm futzing isn't working https://travis-ci.org/rails/rails/jobs/114732815

[bf4]

( @BanzaiMan The goal of the PR is to have a recent JRuby that installs super quick, like the ones pre-installed on the VM, or quick download, use binary, no gemsets, recent bundler etc.)

(going to sleep now 💤, I'll be back online in x hours)

(The --verbose thing turned out to be something in Rake fixed in >= 0.11.1 ruby/rake#120 jruby/jruby#3653 (comment) )
