AutoBoxing working? Follow

Do I have to turn Autoboxing on?
Idea says this code has errors at the underlined areas:

= j) = " + (_i >= j_));
        System.out.println("(i <= j) = " + (_i <= j_));
        System.out.println("(i == j) = " + (i == j));]]>

It compiles and runs fine using JDK 5.0 beta 3
it prints

(i >= j) = true
(i <= j) = true
(i == j) = false

Why is Idea flagging this as an error?
I am doing something wrong or should I submit an SCR?

Thanks,
