ShutdownHookProcessDestroyer

public ShutdownHookProcessDestroyer()

Constructs a ProcessDestroyer and obtains Runtime.addShutdownHook() and Runtime.removeShutdownHook() through reflection. The ProcessDestroyer manages a list of processes to be destroyed when the VM exits. If a process is added when the list is empty, this ProcessDestroyer is registered as a shutdown hook. If removing a process results in an empty list, the ProcessDestroyer is removed as a shutdown hook.
