Hi,
Should StandardCluster.stop() throw a LifecycleException?
StandardCluster.stop () does not throw a LifecycleException when stop () is invoked on
an instance
which has not been started. A message is logged but then the code proceeds and a
NullPointerException could result.
(I don't understand this class well enough to say whether this is really a bug or not,
I could
well be missing something here...)

*/
public void stop() throws LifecycleException {
// Validate and update our current component state
if (!started)
log(sm.getString("standardCluster.notStarted"));
try {
multicastSocket.leaveGroup(multicastAddress);
multicastSocket = null;
} catch (IOException e) {
log(sm.getString("standardCluster.leaveException",
multicastAddress));
}
if (debug > 1)
log(sm.getString("standardCluster.leaveGroup",
multicastAddress));
lifecycle.fireLifecycleEvent(STOP_EVENT, null);
started = false;
// Stop the background reaper thread
threadStop();
}
