[FIXED] How to run jlink-generated Java runtime image without CMD window?

Issue

I've created Java runtime image for a simple OpenJFX application. In order to run this app, jlink auto-generated two lauch scripts under %image_path%/bin directory. This how it looks like (the one for Windows):

@echo off
set JLINK_VM_OPTIONS=
set DIR=%~dp0
"%DIR%\java" %JLINK_VM_OPTIONS% -m app/com.package.Launcher %*

Obviously, when I run this batch file it opens new shell window, which is not what I want to. I've tried all common approaches: use javaw instead of java, run script via start command etc. Nothing works.

Is it possible to avoid shell window or somehow create native launcher?

Solution

Ok, I've figured out it's not posiible to eliminite shell window completely. In the best scenario it's just flickers for ~1sec. This is how it can be achieved:

@echo off
set JLINK_VM_OPTIONS=
set DIR=%~dp0
start "" "%DIR%\javaw" %JLINK_VM_OPTIONS% -m app/com.package.Launcher %* && exit 0

There is a feature request about native laucher implementation but it's not discussed actively.

Nonetheless I've solved the problem. There is "Batch to EXE Converter" tool. It can generate executable (basically the same batch file) which can run your app silently.
