In the previous chapter, we explored Java 9's new stack walker API and learned how it enables Java applications to walk the calling stack. This is a specialized functionality that is not often implemented in Java applications. That being said, the API may be good for some very special cases, such as for functionality that is delivered by a framework. You learned that if you develop framework-supporting application programming and you want code that depends on the caller context, then the stack walker API is for you. We also discovered that the API gives fast and optimized access to the call stack, implementing lazy access to the individual frames.
In this chapter, we will cover 16 Java Enhancement Proposals ...
