Hi all, I have a JRuby app currently running under the Sun JDK on Ubuntu that I would like to try to migrate to OpenJDK before committing it to a production image. Long ago, I did the long exercise of enabling invokedynamic support and found that this particular app really got a boost from it. I think this is a lot easier to do now, but a quick Google search just confused me further. I realized I really haven't looked at OpenJDK and JRuby together for more than a year, and I'm completely at sea.
What's the current thinking from the team as to the best OpenJDK build to run on modern Ubuntu (10.04, most likely) to optimally exercise a JRuby app, with the idea that it's going to be used in production? What switches should I throw to get the most out of invokedynamic and any other OpenJDK-specific advantages for JRuby? Or put another way, "what would Charlie do?" - Rob
