Unit test failures are not related. Looks like it is about time to do a unit test cleanup on branch-2. |

nit: could we factor out the common code into a helper rather than duplicating?

I suppose it is possible to collapse this into a single code block, would that be better? E.g.
boolean doTasks = false;
....
case TASKS:
doTasks = true;
// fall through
case LIVE_SERVERS: {
...
// do stuff
if (doTasks) {
// do tasks stuff too, like the master monitoredtask collection
...
}
