Okay, my bad, I missed a backend_poll call when doing the update.

@ioquatix nice job on the upgrade and release!

[ioquatix]

Thanks - the JRuby release is still a bit painful - but at least it worked in the end.

@ioquatix wish I would've automated the release process with rake forever ago. Oh well
