Can Java throw a null reference to an exception?

Question

Consider this code:

try {
    ....
} catch (MyException e){
    /*Can e be null here?*/
}

Given that null in Java is a typed null reference, is it ever possible that the catch block above will be entered with e as null?

How much investment would it have been to actually write `throw null;` and see for yourself? — Marko Topolnik, Mar 13 '14 at 12:35
Because, for one thing, I'd be concerned as to the *type* of null I'd be throwing. — P45 Imminent, Mar 13 '14 at 21:19

e will never be null. Even if null gets thrown somewhere for some reason, e will just be a NullPointerException.
