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

             Summary: Different WindowAndGroups could end up in one due to hashCode collision

                 Key: GEARPUMP-286
                 URL: https://issues.apache.org/jira/browse/GEARPUMP-286
             Project: Apache Gearpump
          Issue Type: Bug
          Components: streaming
    Affects Versions: 0.8.2
            Reporter: Manu Zhang
            Assignee: Manu Zhang


Currently, we use a {{TreeMap}} to store and sort {{WindowAndGroup}}s, which requires {{WindowAndGroup}}
to be {{Comparable}}. However, {{Group}} is not and not supposed to be so I hacked with its
{{hashCode}} for comparison. That is wrong since two {{Group}}s could have identical {{hashCode}}s.
