Visual VM is a tool that provides information about code running on a Java Virtual Machine. It was provided with Oracle JDK 6, Oracle JDK 7, and Oracle JDK 8.More information about Visual VM can be found on the NetBeans Profiler and Visual VM blog: https://blogs.oracle.com/nbprofiler/ Starting with JDK 9, Visual VM will not be included with Oracle JDK. Developers who would like to use Visual VM with Oracle JDK 9 or later can get it from the Visual VM open source project site.
