>Description:
Some methods when invoced using a null pointer, will generate
a SIGABRT, instead of the NullPointerException one would
expect.

The problem seems only to occur with simple methods such as
Integer.intValue(), String.length(), Vector.size().
>How-To-Repeat:
Compile and run

--------
public class NullPointerExceptionTest {
    public static void main(String[] args) {
        ((Integer) null).intValue();
    }
}
--------

Other one-liners that trigger the same problem:
    ((String) null).length();
    ((java.util.Vector) null).size();
    Boolean ref = null; ref.booleanValue();
