Rookie here -- but it seems as if these 2 commands will wrap the jar file into a working .app bundle with Java 9 and Mac OS 10.13. Only downside (other than more work) is that the Java .app files are pretty large on MacOS as they bundle the necessary JRE. Note - javapackager comes with JDK8+, and hdiutil is MacOS native.
