-----------------------------------
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.
