Scala 2.12 Java 11 Flink 1.13.2 Running in Kubernetes Hi,
While trying to use a configuration with JSONLayout in log4j2 with XML format, we receive the following error when bootstrapping the JM / TM:

https://stackoverflow.com/questions/65062081/java-lang-classnotfoundexception-com-fasterxml-jackson-databind-ser-filterprovi, this happens due to the fact the JM / TM start with a modified classpath that doesn't include jackson-databind. While I could add the jars explicitly to the `lib/` directory in the Dockerfile, this is pretty annoying to maintain as versions evolve. Is there any other workaround for this? or an open issue? -- Best Regards, Yuval Itzchakov.
