* Terminates the currently running Java virtual machine by initiating its
* shutdown sequence. This method never returns normally. The argument
* serves as a status code; by convention, a nonzero status code indicates
* abnormal termination.
*
*
The virtual machine's shutdown sequence consists of two phases. In * the first phase all registered {@link #addShutdownHook shutdown hooks}, * if any, are started in some unspecified order and allowed to run * concurrently until they finish. In the second phase all uninvoked * finalizers are run if {@link #runFinalizersOnExit finalization-on-exit} * has been enabled. Once this is done the virtual machine {@link #halt * halts}. * *
If this method is invoked after the virtual machine has begun its * shutdown sequence then if shutdown hooks are being run this method will * block indefinitely. If shutdown hooks have already been run and on-exit * finalization has been enabled then this method halts the virtual machine * with the given status code if the status is nonzero; otherwise, it * blocks indefinitely. * *
The {@link System#exit(int) System.exit} method is the * conventional and convenient means of invoking this method.
* * @param status * Termination status. By convention, a nonzero status code * indicates abnormal termination. * * @throws SecurityException * If a security manager is present and its {@link * SecurityManager#checkExit checkExit} method does not permit * exiting with the specified status * * @see java.lang.SecurityException * @see java.lang.SecurityManager#checkExit(int) * @see #addShutdownHook * @see #removeShutdownHook * @see #runFinalizersOnExit * @see #halt(int) */ public void exit(int status) { SecurityManager security = System.getSecurityManager(); if (security != null) { security.checkExit(status); } Shutdown.exit(status); } /** * Registers a new virtual-machine shutdown hook. * *
The Java virtual machine shuts down in response to two kinds * of events: * *
A shutdown hook is simply an initialized but unstarted * thread. When the virtual machine begins its shutdown sequence it will * start all registered shutdown hooks in some unspecified order and let * them run concurrently. When all the hooks have finished it will then * run all uninvoked finalizers if finalization-on-exit has been enabled. * Finally, the virtual machine will halt. Note that daemon threads will * continue to run during the shutdown sequence, as will non-daemon threads * if shutdown was initiated by invoking the {@link #exit exit} * method. * *
Once the shutdown sequence has begun it can be stopped only by * invoking the {@link #halt halt} method, which forcibly * terminates the virtual machine. * *
Once the shutdown sequence has begun it is impossible to register a * new shutdown hook or de-register a previously-registered hook. * Attempting either of these operations will cause an * {@link IllegalStateException} to be thrown. * *
Shutdown hooks run at a delicate time in the life cycle of a virtual * machine and should therefore be coded defensively. They should, in * particular, be written to be thread-safe and to avoid deadlocks insofar * as possible. They should also not rely blindly upon services that may * have registered their own shutdown hooks and therefore may themselves in * the process of shutting down. Attempts to use other thread-based * services such as the AWT event-dispatch thread, for example, may lead to * deadlocks. * *
Shutdown hooks should also finish their work quickly. When a * program invokes {@link #exit exit} the expectation is * that the virtual machine will promptly shut down and exit. When the * virtual machine is terminated due to user logoff or system shutdown the * underlying operating system may only allow a fixed amount of time in * which to shut down and exit. It is therefore inadvisable to attempt any * user interaction or to perform a long-running computation in a shutdown * hook. * *
Uncaught exceptions are handled in shutdown hooks just as in any * other thread, by invoking the {@link ThreadGroup#uncaughtException * uncaughtException} method of the thread's {@link * ThreadGroup} object. The default implementation of this method * prints the exception's stack trace to {@link System#err} and * terminates the thread; it does not cause the virtual machine to exit or * halt. * *
In rare circumstances the virtual machine may abort, that is, * stop running without shutting down cleanly. This occurs when the * virtual machine is terminated externally, for example with the * SIGKILL signal on Unix or the TerminateProcess call on * Microsoft Windows. The virtual machine may also abort if a native * method goes awry by, for example, corrupting internal data structures or * attempting to access nonexistent memory. If the virtual machine aborts * then no guarantee can be made about whether or not any shutdown hooks * will be run.
