Problem Description

After packaging, the file "universalJavaApplicationStub" is missing in the MacOS directory within the macOS executable package, preventing the program from running properly.

Cause of the Problem

https://github.com/javapackager/JavaPackager/blob/master/src/main/java/io/github/fvarrui/javapackager/packagers/MacPackager.java

	private void processStartupScript() throws Exception {
		if (this.administratorRequired) {
			// We need a helper script ("startup") in this case,
			// which invokes the launcher script/ executable with administrator rights.
			// TODO: admin script depends on launcher file name 'universalJavaApplicationStub'

			// sets startup file
			this.executable = new File(macOSFolder, "startup");

			// creates startup file to boot java app
			VelocityUtils.render("mac/startup.vtl", executable, this);
		} else {
			File launcher = macConfig.getCustomLauncher();
			if (launcher != null && launcher.canRead() && launcher.isFile()){
				FileUtils.copyFileToFolder(launcher, macOSFolder);
				this.executable = new File(macOSFolder, launcher.getName());
			} else {
				this.executable = preparePrecompiledStartupStub();
			}
		}
		executable.setExecutable(true, false);
		Logger.info("Startup script file created in " + executable.getAbsolutePath());
	}

Expected Result

It is expected that the "universalJavaApplicationStub" can be properly copied to the MacOS directory after packaging. May I ask if there is a fix plan for this issue?
