Version number Description: Kafka is developed using Scala. The previous 2.12 is the version number of Scala, and the later is the version number of Kafka.
Version 0.11 is already a relatively complete version of Kafka. The later versions are all kinds of enhancements to streaming. If it is only used as a message queue, use version 0.11.

According to the actual measurement, the openjdk11 and kafka0.11 installed on this machine are not supported.
I returned to normal after changing to JDK1.8.
You can also choose the updated Kafka version to use, so you don’t need to replace the JDK.
