Description

While it works, the LevelMixIn class for Jackson is coded incorrectly and a problem shows up as https://github.com/FasterXML/jackson-databind/issues/1809 if you updated Jackson from 2.9.1 to 2.9.2. While I would argue this is a regression in Jackson, Jackson contributor think it was lucky this worked at all.

This ticket will apply changes suggested by Jackson and a separate ticket will update to Jackson 2.9.2.
