Native Image build fails

[WARNING] Error: Detected a started Thread in the image heap. Threads running in the image generator are no longer running at image runtime.  To see how this object got instantiated use --trace-object-instantiation=java.lang.Thread. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.
