The jhsdb tool is described on its Oracle JDK 9 Documentation Early Access page, "You use the jhsdb tool to attach to a Java process or to launch a postmortem debugger to analyze the content of a core-dump from a crashed Java Virtual Machine (JVM)." The tool comes with several "modes" and several of these modes correspond in name and function with individual command-line tools available in previous JDK distributions. The jhsdb tool not only provides a single tool that encompasses functionality of multiple other tools, but it also provides a single, consistent approach to applying these different functions. For example, the jhsdb command-line syntax for getting help for each of the "modes" is identical.
