As a workaround, avoid primitives; use, for example, Integer instead.  Then in 
your getter, return its value as a primitive, and also check to see if it's 
null, and if so, set it to whatever default you prefer.

public final class Zzz {
    Integer number;

    public int getNumber() {
        if (this.number == null)
            this.number = Integer.valueOf(0);

        return (this.number.intValue());
    }
