> This is a slightly similar issue to LOG4J2-3367:
> I want to be able to "share" some pattern settings between a line-based logger and a JSON logger, so I created a naive config like this (both logging to console just for demo purposes):
>  
> *log4j2.xml*
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration name="Demo" status="debug" monitorInterval="60">
>   <Properties>
>     <Property name="exFilters">org.junit,org.apache.maven,sun.reflect,java.lang.reflect</Property>
>     <Property name="exPattern">%xEx{filters(${exFilters})}</Property>
>     <Property name="logPattern">%d{ISO8601} %-5p [%c{1}] %m%n${exPattern}</Property>
>   </Properties>
>   <Appenders>
>     <Console name="Json">
>       <JsonTemplateLayout eventTemplateUri="classpath:MyLayout.json" />
>     </Console>
>     <Console name="Plain">
>       <PatternLayout pattern="${logPattern}" />
>     </Console>
>   </Appenders>
>   <Loggers>
>     <Root level="info">
>       <AppenderRef ref="Json" />
>       <AppenderRef ref="Plain" />
>     </Root>
>   </Loggers>
> </Configuration>{code}
> *MyLayout.json*
> {code:java}
> {
>   "msg": {
>     "$resolver": "message"
>   },
>   "thrown": {
>     "stackTrace": {
>       "$resolver": "pattern",
>       "pattern": "${exPattern}"
>     }
>   }
> } {code}
> This doesn't work (probably because the lookup is only done at logging time, not at configuration time), but I'm wondering if this (or something similar) could be implemented somehow...
> Yes, I'm aware that {{ExceptionResolver}} provides something similar, but it's not quite the same as the {{%xEx}} pattern, which seems to be a lot more customizable...
