      Description

      Steps to reproduce:
      1) auto-reloading of log4j 2.x configuration from XML is enabled
      2) system is started and producing logs
      3) change XML configuration, so it's not valid XML any longer
      4) Wait till it would be picked up -> no more logging info is produced, exception can be found from logs (see below).
      5) Fix XML configuration -> it's not getting reloaded anymore, only java restart can fix the problem.

      log4j2.xml org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 7; The processi
