Using the jpackager

You're thinking of the "HelloWorld.exe" example? That's not really informative, since it doesn't specify how to create the contents of the directory, nor the layout of the levels below app/ and runtime/.
I have a runnable jar, let's call it APP.jar.
If I try the naive: jpackager create-image -o out -j APP.jar
Bundler Mac Application Image skipped because of a configuration problem: The configured main jar does not exist APP.jar
Advice to fix: The main jar must be specified relative to the app resources (not an absolute path), and must exist within those resources.
OK, let's do that. Put the jar in an "input dir": jpackager create-image -o out -i in -j APP.jar
Creating app bundle: /Users/lennartb/App/out/App.app
"Adding modules:  to runtime image."
Exception: jdk.tools.jlink.plugin.PluginException: java.io.IOException: jdk.tools.jlink.plugin.PluginException: ModuleTarget attribute is missing for java.base module
Error: Bundler "Mac Application Image" (mac.app) failed to produce a bundle.
I have of course tried a lot of other things, but I'd really like some pointers here...
