Thanks for your interest in Mikka, I'm not exactly actively maintaining it since quite a long time ago, so I'm not really sure what to do about your bug reports and this pull request. I can merge this, but there's a lot of other things that would need fixing too, like it's using an outdated version of Akka at this point, and I don't know how compatible it would be with the later releases.

Do you actively use Mikka, or are you just evaluating it?

[munkyboy]

I'm just evaluating it as a way to utilize Akka through JRuby.

Ok, good to know. If it's ok with you to continue evaluating it as it is, then if you decide on using it I wouldn't mind handing over the maintenance to you, if you want. I won't have time merging and pushing up new gem releases, unfortunately.
