[~ralph_goers@dslextreme.com] We do not have the exact issue. We have an issue using 2.9.0 for our android application which i reported in LOG4J2-2038 

Previously, we were using 2.3. We have a problem with oreo devices with v2.3 which is resolved in 2.9.0 as per the status of LOG4J2-1920. So, we need to use 2.9.0 to avoid crashing for Android oreo devices. We need help to resolve this.

Thanks,
Mounica

> Hi, 
> I integrated the log4j with my Android application and did the initial config. It works fine.  I have a menu item in "Settings" screen where I can change the log levels in my application. So, After I change the configuration, I need to update the loggers. So I am using following logic. 
> {code:java}
> LoggerContext ctx = LoggerContext.getContext()
>         Configuration config = ctx.getConfiguration();
>         LoggerConfig loggerConfig = config.getLoggerConfig(LogManager.ROOT_LOGGER_NAME);
>         loggerConfig.setLevel(myLogLevel);
>         ctx.updateLoggers();
> {code}
> While getting the logger context, I am getting a ClassCastException.
