Chapter 15. Java 9 and the Future
While this book was being written, Java 9 was in active development. The new release contains a number of performance-related features and enhancements that are relevant to the Java/JVM application engineer.
In the first part of this chapter, we survey the new and modified aspects of the platform that a performance engineer should know about in Java 9.
The truth is, for most developers, Java 9 really does consist of “modules and then everything else.” Just as Java 8 was all about lambdas and their consequences (streams, default methods, and small aspects of functional programming), so Java 9 is mostly about modules.
Modules are a new way of building and deploying software and are not easy to adopt piecemeal. They represent a very modern way to build well-architected apps. However, it may take teams and projects a while to see the long-term benefits of adopting modules. For our purposes modules are not of any real performance significance, and so we make no attempt to discuss them in any detail and instead focus on the smaller but performance-relevant changes.
Note
Readers interested in Java 9 modules should consult an appropriate reference, such as Java 9 Modularity by Sander Mak and Paul Bakker (O’Reilly).
