Class ShutdownTimeout

java.lang.Object
  net.java.sip.communicator.impl.shutdowntimeout.ShutdownTimeout

All Implemented Interfaces:

org.osgi.framework.BundleActivator

public class ShutdownTimeout
extends Object
implements org.osgi.framework.BundleActivator

In order to shut down SIP Communicator we kill the Felix system bundle. However, this sometimes doesn't work for reason of running non-daemon threads (such as the javasound event dispatcher). This results in having instances of SIP Communicator running in the background. We use this shutdown timout bundle in order to fix this problem. When our stop method is called, we assume that a shutdown is executed and start a 15 seconds daemon thread. If the application is still running once these 15 seconds expire, we System.exit() the application.

Field Summary

static long	SHUTDOWN_TIMEOUT The number of miliseconds that we wait before we force a shutdown.
static int	SYSTEM_EXIT_CODE The code that we exit with if the application is not down in 15 seconds.

Constructor Summary

ShutdownTimeout()

Method Summary

void	start(org.osgi.framework.BundleContext context) Dummy impl of the bundle activator start method.
void	stop(org.osgi.framework.BundleContext context) Called when this bundle is stopped so the Framework can perform the bundle-specific activities necessary to stop the bundle.

Method Detail

start

public void start(org.osgi.framework.BundleContext context)
           throws Exception

Specified by:

start in interface org.osgi.framework.BundleActivator

Parameters:

context - unused

Throws:

Exception - If this method throws an exception (which won't happen).

stop

public void stop(org.osgi.framework.BundleContext context)
          throws Exception

Called when this bundle is stopped so the Framework can perform the bundle-specific activities necessary to stop the bundle.

Specified by:

stop in interface org.osgi.framework.BundleActivator

Parameters:

context - The execution context of the bundle being stopped.

Throws:

Exception - If this method throws an exception, the bundle is still marked as stopped, and the Framework will remove the bundle's listeners, unregister all services registered by the bundle, and release all services used by the bundle.
