Not the least interesting subchapter of the bean story, because those things were the most pressing oop data + behavior conglomerates that desperately needed disentanglement, and because "truth from the backend" is one of the most obvious use cases for immutability. But The Bean was more than that, just think of that FactoryFactoryBean meme that haunts Java to this day which was (in my perception) the result of that misguided love affair with XML called the XmlApplicationContext. ("who needs a compiler when we have xsd to ensure footgun correctness!")
