Dealing with undefined property gets you a fatal stack

This occurs in the context of nodejar. As soon as a script manipulates an undefined property it gets a fatal exception.

I have isolated to be the conjunction of nashorn:mozilla_compact script being loaded from a script being evaluated from nashorn engine.

Same script executed from nashorn shell works fine.

Run the attached testcase (nb project) to reproduce.
