> Hi, im trying to migrate from log4j 1 to 2.
> Im having problems with migrating from the propertyconfigurator.
> Doing something like
>   @SuppressWarnings("unchecked")
>   private static void reset() throws MalformedURLException, URISyntaxException {
>     LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
>     Configuration config = ctx.getConfiguration();
>     for (LoggerConfig loggerConfig : config.getLoggers().values()) {
>       loggerConfig.setLevel(null);
>     }
>     Configurator.shutdown(ctx);
>     String path = System.getProperty(JAVA_OPTIONS_LOG_CONFIG);
>     if (Strings.isNullOrEmpty(path)) {
>       ConfigurationSource source = ConfigurationSource.fromResource(LOG_CONFIGURATION, null);
>       Configurator.initialize(null, source);
>     } else {
>       URL in = new URL(path);
>       Configurator.initialize((String) null, null, in.toURI());
>     }
>     ctx.updateLoggers();
>   }
> kinds of works but then it closes my other appenders that i started with java.
> See https://gerrit-review.googlesource.com/#/c/gerrit/+/142811/
> please could i have some help as i've spent two weeks on this and havent really moved on.
> We need to reset the loggers back to default when we do
> for example
> ssh -p 29418 admin@localhost gerrit logging set-level \
>      debug com.google.
> ssh -p 29418 admin@localhost gerrit logging set-level \
>      reset
> and also i found that even though i specified ConsoleAppender in log4j2.properties (resources folder in java) it dosen't seem to show any of gerrit logging when starting.
> To work around this i am adding ConsoleAppender through the ErrorLog class.
> (Sorry if this is the wrong place to ask this but i couldn't find any where else).
