Full log dump here

Can you give me four bits of info?

• Java version
• JRuby version
• Mirah version
• Pindah version (I know you wrote 0.13, but what commit are you using?)

I can currently get things working with two configurations:

• Java 6/7, JRuby 1.6.8, Mirah 0.0.12, Pindah from master
• Java 6/7, JRuby 1.7.2, Mirah built from local master, Pindah from master (Mirah build is finicky right now)

There are a couple of different problems that can interplay here, but I'm pretty sure we can get you running.

Ok, followup: after all the compatibility debugging I've done this week, I recognize this error as using Mirah 0.0.12 with JRuby 1.7+.

I'm going to close this, since that's a known bad combination, and we now note that (see #42) in the README. If my reading of the tea leaves is incorrect, please reopen.

@abscondment :+1: Thank you (and everyone) for all the debugging. Sorry I wasn't able to give you the info in a timely fashion but I'll be sure to try out the recommended requirements and report back if there are any issues!

Awesome, thanks!
