Michael Kendle commented on LOG4J2-3082:
----------------------------------------
I spent about a day being very confused at why using `JsonLayout` with Jackson
on the classpath automatically handled things like...
{code:java}
LOGGER.error(new ObjectMessage(myObject), e); {code}
but when I switched to `JsonTemplateLayout` it would only output
`MyObject@538e6abb`.
Having `JsonTemplateLayout` have that feature parity with the more basic
`JsonLayout` would be extremely helpful.

> When using JsonTemplateLayout is there a way to output composite objects as
> JSON?
> It looks like any composite objects are output as simple strings with the
> value generated by the .toString() method of the Java object.
> Is there an option to output JSON instead, possibly using
> _org.apache.logging.log4j.core.jackson.Log4jJsonObjectMapper_ ?
> It is currently possible to do this by converting the object into a
> java.util.Map before supplying it to the logging framework but it would be
> nice if the logging framework did this out of the box if an option is turned
> on as it is not always possible to do this (e.g. with objects on the MDC/NDC).
> This should apply to composite objects logged from...
> # The thread context map (MDC).
> # The thread context stack (NDC).
> # Message parameters
> # anywhere else that I may have missed.
> See the differences between the two log messages generated in the attached
> project.
