             Summary: Potential null dereference in SimpleWindowCounter#poll()
                 Key: EAGLE-984
                 URL: https://issues.apache.org/jira/browse/EAGLE-984
             Project: Eagle
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


Here is related code:
{code}
    public Tuple2<Long, Long> poll() {
        long oldestTimestamp = timeQueue.poll();
        Tuple2<Long, Long> pair = new Tuple2<>(oldestTimestamp, counter.get(oldestTimestamp));
{code}
We should check the return value from timeQueue.poll() before casting to long.
