[MC-33025] No logs created in 13w39 client in singleplayer mode

Noticed today that since the 26/9 i no longer have any client log output when playing singleplayer. Have not tried if there is a difference in multiplayer mode.

I saw the notice about log4j2 and new default logs location being logs and tried creating .minecraft/logs/ but it did not help.

Confirmed.

Adding a log4j2 configuration via -Dlog4j.configurationFile=/home/henrik/.minecraft/logs.xml allows me to successfully configure log output. So seems the problem is in default log4j2 configuration.

This is the log4j2 logs.xml file I used:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Root level="trace">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

Note: No idea what that log format really means and likely not correct for Minecraft. Only copy-pasted from log4j2 example to see if it could be done. But with that there is log output on the console.
