Yes, that AOOB was the one I saw breaking. I'll see if I can find a way to
reproduce your other issue.
OK, I created a simple test that reproduces the NPE. If you run this code,
you'll get an NPE when calling the defined "foo" method from a new
thread; it works if
called from the Main Thread where Ruby was instantiated.
This will give an exception in a different place:
java.lang.NullPointerException

Having debugged the issue in the EclipseShell code, it seems like the
InstructionBundles
EvaluationState returns null for it's "self" field.
Test code attached.
