the error can be reproduced with a very simple Gemfile:

source 'http://rubygems.org'

gem 'httpclient'

and then run JAVACMD=/home/braulio/Projects/GraalVM-0.10/jre/bin/javao bundle exec jruby.bash -X+T -e 'puts Truffle.graal?'

In general we don't support Bundler at the moment, however I think @bjfish has been trying it and I think he said we were nearly there.

@brauliobo to get around bundler we currently use different tool, please have look at https://github.com/jruby/jruby/tree/master/lib/ruby/truffle/jruby%2Btruffle. If you run into trouble I'll help.

Last time I tried rubygems and Bundler it was working very well for me. I think this was the patch I was using:
https://gist.github.com/bjfish/840c11b171450642bdab

I remember I was setting a custom GEM_HOME and using a different ruby to fetch the dependencies like this:

GEM_HOME=/path/to/gem/home gem install sinatra # using ruby 2
GEM_HOME=/path/to/gem/home ruby sinatra_app.rb # using truffle

cool @bjfish! could you create a PR?

I've tried the gist changes, but it does not work at the moment because rubygems versions differ in JRuby stdlib and JRuby+Truffle stdlib. Generated gem bins are not running with older rubygems. The tool is fine.

Thanks for the issue, but I'll close now that we are moving repository. Bundler still isn't quite ready yet in general so we don't expect it to work.
