I have a lot of error messages when starting embedded Cassandra:

Could you please help me to find the reason for these error messages in logs? I have them when I run service locally with embedded Cassandra or run integration tests. All works good but there are a lot of these messages and they produce not needed noise inside logs. I use windows 10 and AdoptOpenJDK (build 11.0.6+10). I launched shopping cart example to reproduce the issue and command sbt lagomCassandraStart.
