[jira] [Commented] (FLINK-22719) WindowJoinUtil.containsWindowStartEqualityAndEndEquality should not throw exception

    [ https://issues.apache.org/jira/browse/FLINK-22719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17348032#comment-17348032 ] 

Andy commented on FLINK-22719:
------------------------------

[~lzljs3620320] I agree with you, If join has two window nodes as input nodes, however join condition does not satisfy window join condition restrict,  it could fall back to regular join.
