Java Singleton Pattern

    Guys, why did my solution with static holder class had some weird assertion? It's definetely the best singleton implementation for Java:

    class Singleton {
    private Singleton() {}

    public static Singleton getInstance() {
        return SingletonHolder.INSTANCE;
    }

    private static class SingletonHolder {
        public static final Singleton INSTANCE = new Singleton();
    }
}
