/**
 * This class tests the cancelJobOnError feature of a task together with task
 * replication. It will start task2, which
 * has "cancelJobOnError" attribute set to true and is also replicated with
 * factor 3 (tesk2replicate and task2merge are necessary because for replication
 * to work). Tasks task2 and task2*2 will sleep for 10 seconds, task2*1
 * will throw an exception after 3 seconds. We check that the job is canceled
 * and that it is possible to retrieve the result of the faulty task (the
 * exception which caused the failure).
