    [ https://issues.apache.org/jira/browse/FLINK-13514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16897214#comment-16897214 ] 

Chesnay Schepler commented on FLINK-13514:
------------------------------------------

This is a timing issue:
{code:java}
streamTask.cancel();

// enable this to reliably reproduce the issue
// Thread.sleep(5 * 1000);

completeAcknowledge.trigger();{code}
