(Almost) Circular class dependencies in Java. What does this print?

CircularStaticDependencies.java

package org.greenrobot;

import java.util.concurrent.atomic.AtomicInteger;

public class CircularStaticDependencies {
    static AtomicInteger count = new AtomicInteger(1);

    static class A {
        static String a1 = "a" + count.getAndIncrement();
        static String a2 = "a" + count.getAndIncrement() + B.b1;
        static String a3 = "a" + count.getAndIncrement() + B.b2;
    }

    static public class B {
        static String b1 = "b" + count.getAndIncrement();
        static String b2 = "b" + count.getAndIncrement() + A.a1;
        static String b3 = "b" + count.getAndIncrement() + A.a2;
    }

    public static void main(String[] args) {
        System.out.println("a1, a2, a3: " + A.a1 + ", " + A.a2 + ", " + A.a3);
        System.out.println("b1, b2, b3: " + B.b1 + ", " + B.b2 + ", " + B.b3);
    }
