 <li><a href="https://issues.apache.org/jira/browse/MESOS-1538">MESOS-1538</a> - A container destruction in the middle of a launch leads to CHECK failure.</li>
 <li><a href="https://issues.apache.org/jira/browse/MESOS-1539">MESOS-1539</a> - No longer able to spin up Mesos master in local mode.</li>
