Beschreibung

ai-triaged bug

When launching a Java program with ${command:SpecifyProgramArgs}, the popup says that I can press 'Escape' to cancel, but it runs anyway.

Environment

Operating System: Windows 11
JDK version: 17.0.4.1
Visual Studio Code version: 1.86.2
Java extension version: 1.28.1
Java Debugger extension version: 17.0.4.1

Steps To Reproduce

Open the repo https://github.com/sbj42/vscode-specifyprogramargs
Open Test.java and press F5.
Pop-up appears with "Press 'Enter' to confirm your input or 'Escape' to cancel".
Press Escape.
Terminal appears and runs the test program with no arguments.

See repo above, but you only need these two files:

Test.java:

public class Test {
    public static void main(String[] args) {
        System.out.println("args: " + String.join(" ", args));
    }
}

.vscode/launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Launch with Arguments Prompt",
            "request": "launch",
            "mainClass": "",
            "args": "${command:SpecifyProgramArgs}"
        }
    ]
}

Verbose output log from "Language Support for Java": log.txt

Current Result

The debug session starts with no arguments.

Expected Result

The debug session should not start, because it was cancelled.

Additional Informations

The implementation of SpecifyProgramArgs is at extension.ts:185. When the user cancels, the function returns a string with a single space. That's indistinguishable from the user entering a space in the input.

I presume that throwing some sort of cancellation exception would be good here, for instance throw new Error('Launch cancelled'). It would be even better if the exception didn't display an error box, but I don't know enough about vscode extension command handlers to know if that's possible.

Alternatively you could just remove the "or 'Escape' to cancel" hint in the input popup.
