Fix NPE in getMdcCopy of LoggingEventInstrumentation

[ygree]

What Does This Do

Fix NPE in getMdcCopy of LoggingEventInstrumentation

Motivation

Even though the exception is caught, it adds overhead and noise to the telemetry data.

Additional Notes

https://github.com/innoq/log4j/blob/master/src/main/java/org/apache/log4j/spi/LoggingEvent.java#L328-L339

 public void getMDCCopy() { if (this.mdcCopyLookupRequired) { this.mdcCopyLookupRequired = false; Hashtable t = MDC.getContext(); // If there is no context, it will be null, so this.mdcCopy will also be null. if (t != null) { this.mdcCopy = (Hashtable)t.clone(); } } }
