> I see that FlowRunEntity methods *getRunId()* and *getMaxEndTime()* does not deserialize in efficient way which causes class cast exception based on the number.
> {code}
>   public long getRunId() {
>     Object runId = getInfo().get(FLOW_RUN_ID_INFO_KEY);
>     return runId == null ? 0L : (Long) runId;
>   }
> {code} 
> and 
> {code}
>   public long getMaxEndTime() {
>     Object time = getInfo().get(FLOW_RUN_END_TIME);
>     return time == null ? 0L : (Long)time;
>   }
> {code} 
> The reason for class caste exception is Json has data type Number which includes all java primitive types. So, if number with in the range of Integer max, then Object is converted to Integer which fails  to type cast to Long.
