Hibernate

Observer the glorious code by your's truly Hibernate:

Java Code:

public class YetAnotherClass
{
    //public static final int YET_ANOTHER_CONSTANT = YET_ANOTHER_CONSTANT; //Compile-time error: illegal forward reference
    public static final int ANOTHER_CONSTANT = YetAnotherClass.ANOTHER_CONSTANT; //OK!

    //public int yetAnotherVariable = yetAnotherVariable; //Compile-time error: illegal forward reference
    public int anotherVariable = this.anotherVariable + 1; //OK!


    public static void main(final String... args)
    {
        System.out.println(ANOTHER_CONSTANT);
        System.out.println(new YetAnotherClass().anotherVariable);
    }
}

Obviously you can not assign a variable to the value of it self before it is declared, hence you
can not write the two commented lines. But if you refer to them in a fully qualified manner, you can!

It is not a bug, it goes hand in hand with the Java specifications.

If you run this code, it prints:
0
1

When value of it the referred to variable is 0, false or null (the default value), if it has not yet been declared.
