In your `log4j2.component.properties` file, properties do not need to be
prefixed with `-D`. So please change
`-DAsyncLoggerConfig.RingBufferSize=5121024` to
`AsyncLoggerConfig.RingBufferSize=5121024`.
Also, the default clock is the system clock. If you want exact timestamps
there is no need to configure a clock. ---
