/**
 * {@link ComputerLauncher#afterDisconnect(SlaveComputer, TaskListener)}
 * <p>
 * EC2 Fleet plugin overrides this method to detect jobs which were failed because of
 * EC2 instance was terminated/stopped. It could be manual stop or because of Spot marked.
 * In all cases as soon as job aborted because of broken connection and slave is offline
 * it will try to resubmit aborted job back to the queue, so user doesn't need to do that manually
 * and another slave could take it.
 * <p>
 * Implementation details
 * <p>
 * There is no official recommendation about way how to resubmit job according to
 * https://issues.jenkins-ci.org/browse/JENKINS-49707 moreover some of Jenkins code says it impossible.
 * <p>
 * method checks {@link SlaveComputer#getOfflineCause()} for disconnect because of EC2 instance termination
 * it returns
 * <code>
 * result = {[email protected]} "Connection was broken: java.io.IOException:
 * Unexpected termination of the channel\n\tat hudson.remoting.SynchronousCommandTransport$ReaderThread...
 * cause = {[email protected]} "java.io.IOException: Unexpected termination of the channel"
