> 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?
