Spring Fu minimal Netty webapp compilation as native image with GraalVM 1.0 RC3

error: Detected a started Thread in the image heap. This is not supported. The object was reached from a static initializer. All static class initialization is done during native image construction, thus a static initializer cannot contain code that captures state dependent on the build machine. Write your own initialization methods and call them explicitly from your main entry point.
