Modular Development with JDK 9
summary
JDK 9 adds a module system that groups packages into modules declared with module-info.java, enforces strong encapsulation so non‑exported packages are inaccessible (GlassFish gets IllegalAccessError when it tries to use a concealed sun.security class), and resolves dependencies at compile and run time with three guarantees: every required module is present, no cyclic module dependencies, and each exported package comes from exactly one module. Migration helpers include automatic modules for existing jars, the analysis tool jdeps, and image builder jlink.
