Comment 1 Philipe Mulet

A return statement inside a method which return type is unbound should 
reproduce it.

Comment 2 Philipe Mulet

2004-07-05 04:56:09 EDT

public class X {
    Zork zork() {
    	return this;
    }
}

Comment 3 Philipe Mulet

2004-07-05 05:02:37 EDT

One of the check for raw types wasn't protected with null check on method type.
Factored out the null check.

Fixed, added regression test: NegativeTest#test432
