---------------------------------------

Hi [~TukeshK],

{{Log4j1ConfigurationParser}} is no longer the default way to parse Log4j 1.x configurations.

I have tried to keep in sync the {{Log4j1ConfigurationParser}} with the more modern {{{}PropertiesConfigurationBuilder{}}}, but it is not a sustainable solution.

If you are looking to convert a Log4j 1.x properties configuration to a Log4j2 XML configuration, you might add a {{writeToXml}} method to the [Builder|https://github.com/apache/logging-log4j2/blob/release-2.x/log4j-1.2-api/src/main/java/org/apache/log4j/builders/Builder.java] interface and implement it in all builders. It is a lot of work, but it would allow us to deprecate {{Log4j1ConfigurationParser}} in the 3.x series.
