In the last chapter, we covered some impressive new features of the Java platform introduced with Java 9, 10, and 11. We focused 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 those regarding the compilation process, type testing, annotations, and automated runtime compiler tests.
This chapter covers some changes to the Java platform that impact variable handlers, import statements, improvements to Project Coin, local variable type inference, root certificates, dynamic class-file constants, and more. These represent changes to the Java language itself.
The specific topics we will cover in this chapter are as follows:
- Variable handlers
- Import statement depreciation warnings
- Project Coin
- Import statement processing
- Inferring local variables
- Thread-local handshakes
- Heap allocation on alternative memory devices
- Root certificates
- Dynamic class-file constants
- Removal of the Java EE and CORBA modules
