In this chapter, we learned how to use the StackWalker and provided example code. Our detailed review of the API included different usage scenarios, options, and information. We explained the API's complexity and shared how and how not to use the class. We closed with some related performance issues that the user has to be aware of.
In our next chapter, we will cover over a dozen Java Enhancement Proposals that were incorporated in the Java 9 platform. The featured changes will cover a wide range of tools and updates to APIs that are aimed at making developing with Java easier and the ability to create optimized Java applications. We will look at the new HTTP client, changes to the Javadoc and Doclet API, the new JavaScript parser, JAR and JRE changes, the new Java-level JVM compiler interface, support for TIFF images, platform logging, XML catalog support, collections, new platform-specific desktop features, and enhancements to method handling and the depreciation annotation.
