Cameron Lee updated SAMZA-2496:
-------------------------------
    Description: TestContainerHeartbeatMonitor does not properly stop the 
ContainerHeartbeatMonitor, so after 2 minutes, it can do a force shutdown of 
the whole test process if the test process is still alive.  (was: 
TestContainerHeartbeatMonitor does not properly stop the 
ContainerHeartbeatMonitor, so after 2 minutes, it can do a force shutdown of 
the whole test process if the test process is still alive.

The force shutdown task is set up using ScheduledExecutorService.schedule. 
ScheduledExecutorService.shutdown does not seem to cancel tasks created using 
the "schedule" method. It seems reasonable to use 
ScheduledExecutorService.shutdownNow when calling 
ContainerHeartbeatMonitor.stop, which will also cancel the force shutdown task.)
