This code throws NPE. But debugger watch window show 'false'

public class ClassTest {

    public static short myConst = 1;

    public static Short getValue() {
        return null;
    }

    public static void main(String[] args) {

        if (getValue()==myConst) {   //This string throws NPE because unboxing                   getValue give us null  
            System.out.println("OK");
        }
    }
}
