I implemented a custom java.util.logging.Formatter to use for our thorntail based apps.
I'm using the formatter as described here https://docs.thorntail.io/2.4.0.Final/#_logging for the property thorntail.logging.custom-formatters.KEY.attribute-class.
Unfortunately I'm not able to access the MDC information in the Formatter, since JUL has no MDC support.
I tried to use MDC.getCopyOfContextMap(), but this always returns null, since we only have NOPMDCAdapter at Runtime
Previously we used a LOG4J config, however this was only applied to our application logs and not to the thorntail logs.
Does someone have an idea how I can use either an Log4J Layout for Thorntail or how I can access the MDC information in JUL.
