By contrast, > org.reflections 0.9.11 does not. It is a breaking change, and Kafka Worker is > impacted. The unit test in attached patch works with org.reflections 0.9.11 > but it fails with org.reflections 0.9.12. > I noticed this issue when running IT of my project with latest Kafka. It is > not a critical breaking but it would be better to keep the behavior > compatibility. Hence, it seems to me that we can revert the update of > org.reflections and then wait for the > [issue|https://github.com/ronmamo/reflections/issues/273]. > > -- This message was sent by Atlassian Jira (v8.3.4#803005)
