== Building Modules for the Java Module System

Since Java 9, Java itself offers a https://www.oracle.com/corporate/features/understanding-java-9-modules.html[module system] that allows for strict encapsulation during compile and runtime.

 * Allows objects that support the [Java Object Serialization](https://docs.oracle.com/javase/8/docs/platform/serialization/spec/serialTOC.html)
