Bug: No such command in #{ruby_version} of ruby - seems to happen for JRuby

[PragTob]

It seems to only happens with jruby. I just wanted to install JRuby 9.1.6.0. Then this error happened whenever I wanted to execute anything with that ruby version. I updated asdf and the ruby plugin, uninstalled, installed again... tried asdf reshim ruby but it all didn't seem to help.

So right now I can't use JRuby :(

tobi@comfy ~ $ ruby server.rb 
No such command in jruby-9.1.6.0 of ruby

see the slightly longer version for more information...

tobi@comfy ~ $ asdf list ruby
2.3.1
jruby-9.1.5.0
jruby-9.1.6.0
tobi@comfy ~ $ asdf local 2.3.1
Usage: asdf local <name> <version>
tobi@comfy ~ $ asdf local ruby 2.3.1
tobi@comfy ~ $ ruby server.rb
tobi@comfy ~ $ asdf local ruby jruby-9.1.6.0
tobi@comfy ~ $ ruby server.rb 
No such command in jruby-9.1.6.0 of ruby
tobi@comfy ~ $ asdf list ruby
2.3.1
jruby-9.1.5.0
jruby-9.1.6.0
tobi@comfy ~ $ ruby -v
No such command in jruby-9.1.6.0 of ruby
tobi@comfy ~ $ 

I'm on Linux Mint 18 if it helps.

tobi@comfy ~ $ uname -a
Linux comfy 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:39:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Any help would be welcome, because maybe I do something wrong. I think it used to worok with 9.1.5.0.

I might be an idiot. JRuby doesn't seem to come with a ruby command, which is weird... I might need to find a place where I pass a link. If someone finds this... jruby -v and jruby server.rb work.
