JRuby on rails encoding error

Question

Yesterday I tried to switch from MRI to JRuby and I believe that i got all the gems right.

I am using Mongoid and not ActiveRecord so no switching of gem necessary there I think.

The error I get is:

incompatible character encodings: UTF-8 and ASCII-8BIT

The Full trace can be shown here: https://gist.github.com/1305847

And my Gemfile can be shown here: https://gist.github.com/1305882

Does anyone have a clue to what the solution might be?

Answer 1

It turns out there was a problem with jruby 1.6.4. After upgrading to 1.6.5 it works fine.

Answer 2

Try with running JRuby in 1.9 mode:

$ jruby --1.9 rails s

You can also $ export JRUBY_OPTS=--1.9
