    Description

      When parsing appender filters configured in the properties file for example:

      log4j.appender.LOG_REQUEST_START_DB=my.appender.class
      log4j.appender.LOG_REQUEST_START_DB.filter.ID=my.filter.class

      a NullPointerException is thrown on line 564 of org.apache.log4j.config.PropertiesConfiguration. The next variable is always null at that point, from what appears to be a bug in the if condition above (looks like it should be head == null instead of head != null).

       

      Note: this is using the log4j1.compatibility=true property
