rubygems IOError: Function not implemented (https://rubygems.org/latest_specs.4.8.gz

Question

I installed Oracle Java on FreeBSD 10:

bb@rails:~/redmine-2.5.1 % java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Server VM (build 25.5-b02, mixed mode)

Also, I have jruby 1.7.12 under rbenv running on top of that:

bb@rails:~/redmine-2.5.1 % jruby -v
jruby 1.7.12 (1.9.3p392) 2014-04-15 643e292 on Java HotSpot(TM) Server VM 1.8.0_05-b13 +indy [linux-i386]

jirb works just fine:

bb@rails:~/redmine-2.5.1 % jirb
irb(main):001:0> 2+3
=> 5
irb(main):002:0>

When I try to install a gem (the first one I need is bundler), I get an odd error message:

bb@rails:~/redmine-2.5.1 % jruby -S gem install bundler
ERROR:  Could not find a valid gem 'bundler' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - IOError: Function not implemented (https://rubygems.org/latest_specs.4.8.gz)

I've tried to download rubygems from http instead, but results aren't any better:

bb@rails:~/redmine-2.5.1 % jruby -S gem install bundler --source http://rubygems.org/
ERROR:  Could not find a valid gem 'bundler' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - IOError: Function not implemented (https://rubygems.org/latest_specs.4.8.gz)
          Unable to download data from http://rubygems.org/ - IOError: Function not implemented (http://rubygems.org/latest_specs.4.8.gz)

Any help appreciated!

I found two solutions:

1. Install Oracle Java + JRuby on the FreeBSD host itself, not inside a jail.
2. User Rubinius or MRI instead
