Randomly getting error: Failed to lanuch debuggee in terminal: com.sun.jdi.connect.TransportTimeoutException

Environment
  • Operating System: Debian GNU/Linux 12 x86_64
  • JDK version: openjdk 17.0.7
  • Visual Studio Code version: 1.79.2 (vscodium)
  • Java extension version: v0.25.2023042006
  • Java Debugger extension version: v0.51.0
Steps To Reproduce

It occurs completely randomly, and can be for any java code.

I managed to reproduce it:

  1. Create a simple Test.java.
sample project
package com;

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int i = scanner.nextInt();
    }
}
  1. Start the program, enter 1 in the terminal, press Enter.
  2. Repeat step 2 until error occurs. (10 ~ 30 repeats)
  3. After randomly repeating, from now on the program freezes every time, and after 20 seconds later a message always pops up, saying Failed to lanuch debuggee in terminal. Reason: com.sun.jdi.connect.TransportTimeoutException

launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Test",
            "request": "launch",
            "mainClass": "com.Test",
            "projectName": "temp_43be885e"
        },
        {
            "type": "java",
            "name": "Current File",
            "request": "launch",
            "mainClass": "${file}"
        },
        {
            "type": "java",
            "name": "App",
            "request": "launch",
            "mainClass": "App",
            "projectName": "temp_43be885e"
        },
        {
            "type": "java",
            "name": "Main",
            "request": "launch",
            "mainClass": "com.Main",
            "projectName": "temp_43be885e"
        }
    ]
}

It doesn't happens a lot when I try to reproduce it.

Additional Informations
  • It occurs completely randomly, and can be for any java code.
  • Cleaning java workspace could temporarily fix.
  • Downgrading the extension to 0.50.0 doesn't fix it. It didn't occur to me in the few months ago.
  • Downgrading the extension to 0.49.0 and 0.46.0, doesn't seem to be able to reproduce (but it's hard to tell because it is random).
  • Adding "java.debug.settings.console":"internalConcole" in User/settings.json seems to fix it, but I cannot use the terminal to enter inputs now. reference
