Adding meta-data to json-logger via YamlConfigurationExtension results in ClassCastException

XMLWordPrintable

      I'm getting a ClassCastException when I try to add "meta-data" to a json-logger within subsystem "logging".

      As this is a new feature and documentation/examples are rare I am not confident that I created the yaml file semantically correct. But no matter how I define the yaml - as soon as "meta-data" is added to the yaml (and no matter what content it provides), the application server fails to boot with this stack trace:

      16:02:18,511 ERROR [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0055: Caught exception during boot: java.lang.ClassCastException: class org.jboss.as.controller.SimpleMapAttributeDefinition cannot be cast to class org.jboss.as.controller.ObjectTypeAttributeDefinition (org.jboss.as.controller.SimpleMapAttributeDefinition and org.jboss.as.controller.ObjectTypeAttributeDefinition are in unnamed module of loader 'org.jboss.as.controller@19.0.0.Beta12' @5ed828d)

      This is the YAML content I tried (with various alternatives but always with the same result)
