@reta any idea for the test failures? Most of them are failing with the below reason

@owaiskazi19 this is one of the changes that went into Log4j 2.20: https://issues.apache.org/jira/browse/LOG4J2-3644, I suspect that our test framework expect no log statement to be emitted but there are some (like such deprecations).
