-------------------------------------

Interesting. Given the need to compile this with javac 1.9, would this be a separate module then?

> 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.
