--------------------------------

             Summary: TimeWindows#windowsFor misidentifies some windows if TimeWindows#advanceBy
is used
                 Key: KAFKA-3784
                 URL: https://issues.apache.org/jira/browse/KAFKA-3784
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 0.10.0.0
            Reporter: Tom Rybak
            Priority: Minor


Using a time window of size 6 minutes with a 5 minute advanceBy results in some of the timestamped
data being inserted into the previous overlapping window even though the event's timestamp
> that window's end time. 

The fault lies in TimeWindows#windowsFor which does not check that all the windows it's adding
have an endTime > event's timestamp.
