In this chapter, we covered some impressive new features of the Java platform, with specific focus on javac, JDK libraries, and various test suites. Memory management improvements, including heap space efficiencies, memory allocation, and improved garbage collection represent a powerful new set of Java platform enhancements. Changes regarding the compilation process resulting in greater efficiencies were part of our chapter. We also covered important improvements, such as with the compilation process, type testing, annotations, and automated runtime compiler tests.
In the next chapter, we will look at several minor language enhancements introduced in Java 9.
