When you start a new project in Java, obviously you are not going to use only plain vanilla Java. You usually need some libraries or frameworks to help you: maybe to connect to a database, maybe to setup some web service. There are many of these libraries and frameworks that have been around our Java ecosystem for a long time. They have helped evolved the Java ecosystem for decades. These libraries experiment with features and how to implement them in the best way. That generated a knowledge base that the developers of the language can later use to add those same features in the best way possible to the core language. ...

Without touching its code, we should be able to “hook” to other objects that are pending status changes and act accordingly. This “hook” must be turned on and off dynamically at runtime. ...
