More discussion in the following PR that includes a > fix: > https://github.com/apache/kafka/pull/2876/files#r112413428 > This issue caused a Streams system test to fail, see KAFKA-4755. > We should fix the regression before releasing 0.10.2.1. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
