Episode 18 “Java's steady march towards strong encapsulation” [AtA]

With JEP 403, Java 17 will strongly encapsulate the JDK internals. This is the latest step in a process that began in Java 9 with the modularization of the JDK. In this episode, Alan Bateman joins Chad to discuss the importance of strong encapsulation, the history, how this will affect your applications today, and what to do in order to prepare for it.
