> I am trying to use Regexfilter in RollingFileAppender. For 1st matching instance it retreived
the logger, but after that I different patttern but nothing is logged in the file. Here is
what I am using:
> Main Class:
> public class MainApp {
> 	/**
> 	 * @param args
> 	 */
> 	public static void main(String[] args) {
> 		// TODO Auto-generated method stub
> 		final Logger logger = LogManager.getLogger(MainApp.class.getName());
> 	
> 		ApplicationContext context = 
>             new ClassPathXmlApplicationContext("Beans.xml");
> 		
>      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");
>      logger.trace("NPF:Trace:Entering Log4j2 Example.");
>      logger.debug("NTL:debug Entering Log4j2 Example.");
>      obj.getMessage();	
>      Company comp = new Company();
>      comp.setCompName("ANC");
>      comp.setEstablish(1889);
>      
>      CompanyBusiness compBus =      (CompanyBusiness)context.getBean("compBus");
>      compBus.finaceBusiness(comp.getCompName(), comp.getEstablish());
>     logger.trace("NTL: Trace: Exiting Log4j2 Example.");
> 	}}

> When I ran for the first time, in my logfile I got logs having only "business" related
line. Latter I changed the patter from .*business*. to "business", logging did not happen
in file nor on the console. Also my application terminated without any kind of logging.
> Then I tried to revert back the pattern to .*business*., thereafter no logging happened
on the log file, but on the console all the log trace is printed. When I comment out the Regexfilter
after trying for long time, my logs was printed in the log file.
> I am not sure if this is a bug of Regexfilter works only for one time. Also if we do
not pass any patter matching characters, the application stops without any log printing either
on console or file.
