What is the lifecyle of a VisualVM plugin?
A plugin’s life begins when it is installed into VisualVM. It can be installed through the VisualVM Plugin Manager (accessed from the Tools menu) or when you run it from NetBeans IDE. The entry points implemented in a plugin must be initialized in a class that extends org.openide.modules.ModuleInstall. They must also be uninstalled through that class. Initialization occurs in the ModuleInstall.restored method and uninstallation through the ModuleInstall.uninstalled method. Every example of VisualVM extension points includes an example of the entry points initialization and uninstallation, such as in the Getting Started Extending VisualVM document.
