I use MRI in dev and production, but the concurrency options in JRuby make me curious enough to give it a go every few months.
Each time I try to get MRI 1.9 compatible code running on JRuby I hit issues that discourage me enough to give up for another few months. I tried last week and hit two issues [1] and [2]. I tried a few months ago and hit [3]. It feels like their 1.9 support is still not production ready. You're right to mention stacktraces as an issue too. When things go wrong you often get a 400 line java stack trace with no relevance to your ruby code. It's traumatising. All that said, @headius is super responsive so hopefully things will continue to improve.
