Hi!

We are upgrading to ActiveRecord 4.0.13 which requires ActiveSupport 4.0.13 which requires thread_safe 0.1.0 or later. The Ruboto tooling unpacks the gem files from thread_safe into our app and expands the included jar from the gem into our app. The tooling also adds an initialization script to activate the JRuby extention service:

require 'jruby'
public
Java::thread_safe.JrubyCacheBackendService.new.basicLoad(JRuby.runtime)

This runs OK, but later we get this exception:

I am not sure where to start debugging this. Our app runs well with ActiveRecord 3.2.x, but with ActiveRecord 5 coming this year, version 3.2 is getting really old, and we need to upgrade.

Any help is appreciated.
