Summary

In this chapter, we covered 16 JEPs that were incorporated into the Java 9 platform. These JEPs cover a wide range of tools and updates to APIs to make developing with Java easier, with greater optimization possibilities for our resulting programs. Our review included a look at the new HTTP client, changes to Javadoc and the Doclet API, the new JavaScript parser, JAR and JRE changes, the new Java-level JVM compiler interface, the new support for TIFF images, platform logging, XML Catalog support, collections, and the new platform-specific desktop features. We also looked at enhancements to method handling and the deprecation annotation.

In the next chapter, we will cover concurrency enhancements introduced with the Java 9 platform. Our primary focus will be the support for reactive programming that is provided by the flow class API. We will also explore additional concurrency enhancements introduced in Java 9.
