[jira] [Commented] (KAFKA-15106) AbstractStickyAssignor may stuck in 3.5

    [ https://issues.apache.org/jira/browse/KAFKA-15106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17735790#comment-17735790 ] 

Kirk True commented on KAFKA-15106:
-----------------------------------

[~flashmouse] Thank you for the test case. I was able to reproduce the hanging behavior. I would have assumed that the {{@Timeout}} would have stopped the test after 90 seconds, but it didn't appear to when I ran it 🤔

I'm not familiar with this area of the code, so I'm not sure if the stated values make for a valid test or not 🤷‍♂️

Were you planning to provide a patch to fix the issue?

Thanks!
