Ralph Goers commented on LOG4J2-1359:
-------------------------------------

It would be a direct replacement for the method in ReflectionUtil and calcLocation in Log4jLogEvent.

> Based on the functional nature of this API, supporting it may require compiling at least
one class using javac 1.9 and reflectively loading it in ReflectionUtil similar to how Spring
supports newer JDK APIs.
> Without support for StackWalker, ReflectionUtil will fall back to using a slower API
in Java 1.9. This is because the Reflection class is a sun-internal class which are no longer
exported to non-JDK code without setting special command line flags.
