Description

In a web application, I am first creating a loggerContext and it log4j.xml  has ${web:rootDir} for lookup. It is resolved as expected. 

I am removing the older loggerContext and using Configurator.initialize(contextName, classlodaer, filePaths, context). This API fails and I can observe that inside weblookup it is NOT getting servletContext. Below API returns null. 

ServletContext ctx = WebLoggerContextUtils.getServletContext();
