Gary Gregory commented on LOG4J2-319:
-------------------------------------
The real bug is that when using %style, the pattern parser in the config does
not know that exceptions may be used in the style pattern. Since it does not
know, the parser adds exception logging (based on the alwaysWriteExceptions).
The attached patch fixes that.

> Note that the last one includes jar provenance.
> The patter in /log4j-core/src/test/resources/log4j2-console-style-ansi.xml is:
> %style{%d{ISO8601}}{black} %style{[%t]}{blue} %style{%-5level:}{yellow}
> %style{%msg%n%throwable}{green}
> When I switch the test to use
> /log4j-core/src/test/resources/log4j2-console.xml, the output contains a
> single track trace without jar provenance. The patter there is:
> %d{ISO8601} [%t] %-5level: %msg%n%throwable
> Looks like a bug in pattern/layout parsing?
