> RingBufferLogEvent::mergePropertiesIntoContextMap is called in the background (consumer) thread for each event.
> If configuration properties are specified it allocates the following temporary objects:
> * make mutable copy of the ThreadContext map
> * iterator over configuration properties map
> * for config values containing ${} placeholders, call {{StrSubstitutor.replace}} (which creates multiple temporary objects)
> (If configuration properties are not specified, no temporary objects are allocated.)
