Hey people,

I've just reported an issue on Adhearsion when using the latest gem versions: adhearsion/adhearsion#549

What I found is that in the context of our adhearsion app, Celluloid crashes un jruby when upgrading to activesupport 4.2.1, but not on MRI. Moving back to 4.1.0 solves the problem.

I'm still trying to reduce the issue to a simple case, but this is what I've found so far:

Any insights are greatly appreciated.

NOTE: MRI 1.9.3 as well as 2.1.5 works.
