[jira] [Comment Edited] (KAFKA-8289) KTable, Long> can't be suppressed

    [ https://issues.apache.org/jira/browse/KAFKA-8289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16832582#comment-16832582 ] 

Vahid Hashemian edited comment on KAFKA-8289 at 5/3/19 3:39 PM:
----------------------------------------------------------------

[~vvcephei] Since, according to your earlier comment, there seems to be a workaround for the reported issue, I didn't think this was blocking the bug fix release, and thought it could be included in a follow-up release. In any case, it seems that the fix is merged to trunk. Is there a reason this ticket is not resolved yet?
