Truffle - Compile Error until when break in case statement

[bjfish]

This fails with the following error in Truffle but not in jruby or ruby 2.2

       x = 0
       until x > 5
          test = "test"
          case
          when test == "hello"
             break unless test == "foo"
             puts "hello"
          when test == "te"
            if test == "false"
              raise "foo"
            end
            break
          else
            puts "else"
          end
          x += 1
      end

Error output

I didn't know you could do that!

This is likely an error in the translator, but I'm not sure what off the top of my head. It's strange that it's a syntax error though - as we run the same parser as JRuby and you say it works there.

System.err.printf("%s:%d: Invalid break%n", node.getPosition().getFile(), node.getPosition().getLine() + 1);

while works fine
