Section 6 of the jpackage command

Override jpackage Resources

states:

"Post-image script, application-name-post-image.wsf. Custom script that is executed after the application image is created and before the MSI installer is built for both .msi and .exe packages. No default script is provided."

So, let's say my "application-name" contains a space such as "My App". What is the file name of my .wsf file? Is it:

My App-post-image.wsf

Because using such a .wsf file name, jpackage is not running my script post installation.

I have also tried "My-App-post-image.wsf" and "My_App-post-image.wsf" both of which also are not launched.

Thus, is there a way of solving an "application-name" that contains one or more spaces or is this a bug/deficiency of the jpackage command?
