What are minimum requirements for running Desktop Compose App on Mac OS and Windows OS

Question

I am developing an app with Desktop Compose Multi-Platform.
It will run on both Mac OS and Windows OS.

The official document(Document Link) states that, in order to build .dmg and .msi executable we need at least JDK 15.
I was able to build a .dmg installer and installed it on MacOS.
But the app does not open and no error message is shown (nothing happens on opening the app)

So my questions are:

1. What minimum JDK version will be required to run this app?
2. Do we need to JDK15 or higher installed on the machine that will run this app ?
3. What are other minimum software / hardware requirements for running a Desktop Compose Multiplatform app ?

Note: I am posting these queries as there is no official document around the following topic:
Minimum software requirements for running Desktop Compose Multiplatform App.

Answer 1

I've ran into this issue before using JPackage with my desktop compose app to create a .dmg executable. As far as I know, the issue shouldn't be in the JDK version you have installed. In my case, the app would show up installed, but when I clicked it, it would try to run and then close immediately without showing any UI.

The problem ended up being that I was trying to get the parents process ID which didn't work specifically on mac.

If you aren't trying to access any system info/process' in your case, the other possibility is some sort of permissions issue so you could try running it from terminal with sudo.

The final thing to try is doing a "manual debug". Creating a file in the start of the app and adding write lines throughout to narrow down exactly where the app is crashing.
