My application uses ScriptingContainer from within jruby as a way to sandbox a work routine. During this work, I need to execute code back in the main jruby instance.

require 'java'
sc = org.jruby.embed.ScriptingContainer.new(org.jruby.embed.LocalContextScope::THREADSAFE)
sc.runScriptlet 'def foo(a); a.call end'
a = proc { begin; raise StandardError; rescue; end }
sc.callMethod(sc.runScriptlet("Kernel"), "foo", a)

This generates a
TypeError: assigning non-exception to $!

Is there another way to accomplish this and workaround this issue?

I ended up using a monitor to control serial execution between jruby and the sub-ScriptingContainer

Yes, unfortunately Ruby objects passing between runtimes generally just doesn't work. They are most definitely tied to their home runtime.

Your solution sounds like a good one!
