[jira] [Commented] (BEAM-1022) StateNamespace should not use Java object equality when comparing windows

    [ https://issues.apache.org/jira/browse/BEAM-1022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15977973#comment-15977973 ] 

Thomas Groh commented on BEAM-1022:
-----------------------------------

Specifically, https://github.com/apache/beam/blob/master/runners/core-java/src/main/java/org/apache/beam/runners/core/StateNamespaces.java#L211 uses the window for the Cache Key, but there is no requirement that window defines a meaningful {{equals}} or {{hashCode}}
