Ralph Goers commented on LOG4J2-2633:
-------------------------------------
I have applied a patch that will log a warning when calcLocation encounters a
NoSuchElementException. Please make sure you have status="WARN" set in your
log4j configuration and provide the resulting log message when it occurs. The
message should only be logged once during the execution of the application
although it is possible the exception might happen more than that.

> When using the Console appender with PatternLayout I was able to see the
> missing logs.
> Looking at my config I noticed that I set the JSONLayout.locationInfo to
> true. After changing it to false I was able to see my logs with the the
> JSONLayout properly.
> I did saw some logs when setting SONLayout.locationInfo to true, for example
> logs from the com.google.common.cache.LocalCache class (sorry but I can't
> share the actual exception due to legal reasons).
> I'm not familiar with the log4j internals, but this seems like an issue with
> Java 11 (or maybe > 8) and the JSONLayout.locationInfo setting.
