IGNITE-6362: NPE in Log4J2Logger 1. There was an issue inside Log4J2Logger.createConsoleLogger(). null was passed instead of LoggerContext during ad-hoc logger creation via LoggerConfig.createLogger() 2. There were issues with unit tests: Log4J2Logger holds context (static) for all logger instances and it is not expected to re-configure it on the fly. That was the issue to run tests one-by-one with different log configuration. A new method Log4J2Logger.cleanup() was implemented to terminate the Log4J logger context.
