You could try pushing an appropriate JSContext on the stack...

Note that you might need to do this anyway, because there might be JS 
running while your code runs (above your code on the callstack), so even 
if we went back to allowing the get if the subject principal is null it 
would randomly fail depending on what JS was calling you.
