MemoryArhivist holds on to any number of ArchivedExecutionGraph's these ArchivedExecutionGraph instances contain a
failureCause field of type ErrorInfo that wrap the exception in case one was thrown to terminate the job
This exception class will more often than not have been loaded by a user code classloader and as long as the
