> The web frontend always displays for the latest finished job in the history that it has an accumulator with name {{JobID (SerializedListAccumulator)}} and value {{org.apache.flink.api.common.accumulators.SerializedListAccumulator}}. This seems to an artifact of the way we send accumulators via akka. Maybe the {{SerializedListAccumulator}} is always collected in the JobManager's {{AccumulatorManager}} no matter whether the job used accumulators or not. Then, this accumulator is returned to the web frontend as long as no other job was started.
