This seems to be an issue with the {{migrateLegacyConfigurationToStandardYaml}}
method, where the configuration parameters in the converted {{config.yaml}} are
by default treated as strings.
This causes problems when trying to change the default configuration, as seen
in the error related to the {{DefaultRolloverStrategy}} plugin. An older ticket
addresses this issue by setting default values for the configuration (log.max),
but the problem persists when attempting to modify these default configurations.
For reference, here is the related JIRA ticket and commit:
