Hmm, maybe it could go as a util class then for now, particularly since
it's package private.
> Investigate ThrowableProxy performance
> --------------------------------------
>
> Key: LOG4J2-2391
> URL: https://issues.apache.org/jira/browse/LOG4J2-2391
> Project: Log4j 2
> Issue Type: Task
> Affects Versions: 2.11.1
> Reporter: Carter Kozak
> Assignee: Carter Kozak
> Priority: Major
>
> I've noticed when applications get into a state where they log more
> exceptions than usual (e.g. network connectivity issues) thread dumps contain
> many threads working inside of ThrowableProxy, loading classes.
> A simple jmh benchmark of a pattern layout writing to disk with a message and
> throwable appears to write about 160,000 events/second using a throwable, and
> 2,000 events/second using ThrowableProxy.
> I will investigate to understand where the substantial difference is coming
> from, and clean up the benchmarks to add to the log4j2 benchmarking module.
