Hi Tharindu, According to chat we had, IMO if your intention is to avoid error messages from "XMLHttpRequestHostObject.java" rather than patching XHR, you can add following to your log4j property file.
log4j.logger.<your package> = DEBUG|INFO|OFF|WARN... log4j.logger.org.jaggeryjs.hostobjects.xhr.XMLHttpRequestHostObject = FATAL or Note that i used log level "FATAL" over completely turn off logging using "OFF".
