Description

Our production environment suffers from

java.lang.NullPointerException at org.apache.logging.log4j.core.async.AsyncLogger.log(AsyncLogger.java:273)
    at org.apache.logging.log4j.spi.AbstractLoggerWrapper.log(AbstractLoggerWrapper.java:121)
    at org.apache.logging.log4j.spi.AbstractLogger.info(AbstractLogger.java:1006)

    at org.springframework.context.support.AbstractApplicationContext$1.run(AbstractApplicationContext.java:809)

It looks like something in our app is still logging despite the AsyncLogger having been stopped (and the disruptor field set to null).

The logger could print out a more informative message in this situation.
