Stack-Walking API

Introduction

Prior to Java 9, access to the thread stack frames was limited to an internal class sun.reflect.Reflection. Specifically the method sun.reflect.Reflection::getCallerClass. Some libraries relies on this method which is deprecated.

An alternative standard API is now provided in JDK 9 via the java.lang.StackWalker´╗┐ class, and is designed to be efficient by allowing lazy access to the stack frames. Some applications may use this API to traverse the execution stack and filter on classes.
