Chapter 2. Discovering Java 9
Java 9 represents a major release and consists of a large number of internal changes to the Java platform. Collectively, these internal changes represent a tremendous set of new possibilities for Java developers, some stemming from developer requests, others from Oracle-inspired enhancements. In this chapter, we will review 26 of the most important changes. Each change is related to a JDK Enhancement Proposal (JEP). JEPs are indexed and housed at openjdk.java.net/jeps/0. You can visit this site for additional information on each JEP.
Note
The JEP program is part of Oracle's support for open source, open innovation, and open standards. While other open source Java projects can be found, OpenJDK is the only one supported by Oracle.
In this chapter, we will cover changes to the Java platform. These changes have several impressive implications, including:
- Heap space efficiencies
- Memory allocation
- Compilation process improvements
- Type testing
- Annotations
- Automated runtime...
