> When a situation occurs where a VM hangs in the "Starting" state for longer than the job.expire.minutes, and the job is deleted from the system, a null pointer exception will occur because the work VO will be null inside of advanceStop in VirtualMachineManagerImpl.java .  I have attached a snippet of a log file of this NPE occurring in the wild.
