jpackage Failed to Launch JVM with 3rd party jars without jmods

Hi!

I am trying to make an exe for my Java project, and for that I tried to use the following cmd:

jpackage -t app-image --name "App Name" --vendor "Vendor" --app-version 1.0 --input "E:\Jar" --dest "E:\Release" --main-jar "My App.jar" --icon "E:\Icon.ico" --module-path "C:\Program Files\Eclipse Adoptium\jdk-21.0.8.9-hotspot\jmods;E:\ProgramUse\Java\JavaFX\javafx-jmods" --add-modules java.base,java.datatransfer,java.desktop,java.sql,javafx.base,javafx.controls,javafx.graphics

But when the exe is made I get "Failed to Launch JVM".

If I use that cmd on a different project it is working fine. BUT the main difference is that the other project doesn't have 3rd party jars other then JavaFX for which I have the jmods.

For the project with the problem I am using other jars as well, and when I am running:

jdeps --multi-release 21 --list-deps --ignore-missing-deps --module-path "E:\ProgramUse\Java\JavaFX\sdk\lib;E:\ProgramUse\Java\Jars\ProjectRequired" "E:\Jar\My app.jar"

I get this:

jakarta.mail
java.base
java.datatransfer
java.desktop
java.sql
javafx.base
javafx.controls
javafx.graphics
org.bouncycastle.lts.prov

And from that I guess the problem is jakarta.mail and org.bouncycastle.lts.prov.

How do I handle this scenario? I do not have the jmods for both of them. All the jars are included in the runnable jar made by Eclipse.

So it turns out that I was getting that error because of connection to DB which was in void main for testing, but now I moved it on a button press:

con = DriverManager.getConnection(db, userDB, passDB);

The thing is, in Eclipse it is working fine, but in packed form, when I call that it just hangs, it doesn't advance. I did a little test around it and the status stays at "Starting connecting".

statusDB.setText("Starting connecting");
			Thread thread = new Thread(new Runnable() {
				public void run() {
					try {
						con = DriverManager.getConnection(db, userDB, passDB);
						Platform.runLater(new Runnable() {
							@Override
							public void run() {
								statusDB.setText("Connected");
							}
						});
					} catch (Exception e) {
						e.printStackTrace();
						FunctionsCode.writeError(e);
						con = null;
						Platform.runLater(new Runnable() {
							@Override
							public void run() {
								statusDB.setText("Failed");
							}
						});
					}
				}
			});
			thread.start();

I am using PostgreSQL. Why does it hang in packed form?
