Expect.throws(null) behaviour undocumented and possibly inappropriate

What steps will reproduce the problem?

1. Invoke Expect.throws(null)
2. Observe the complete lack of anything unusual.

Null does not throw an exception, but causes one: ObjectNotClosureException, yet it is caught within Expect.throws() and handled as any other.

Please clarify whether this behaviour is intended in method documentation and possibly update the method itself to handle this case separately.
