Carter Kozak commented on LOG4J2-3266:
--------------------------------------
Not directly related to the reported problem, but you seem to be doing a
context-map lookup for a ThreadName property – if that's set from
{{java.lang.Thread.getName()}}, you may want to use {{${event:ThreadName}}}
instead, which uses the thread name associated with the LogEvent itself (no
interactions with the ThreadContext/MDC required).
