Looking at the code, it's adding a log event property named "application"
if you set it.
Digging into LoggingEvent, it appears that properties are a synonym for the
MDC. So, MDC.put("application", "some-name") would do it.
Related, I'd recommend upgrading to Log4j 2.x as 1.x is EOL and is not
supported in Java 9 and beyond due to various bugs.
