when I type taskkill /f /t /pid xxx in Command Prompt, my process tree ends correctly. However, the code block below written in Java ends all processes in my process tree except one of them. Could you help me?

String pid = getPidWithSomeWay();
ProcessBuilder pb1 = new ProcessBuilder("cmd.exe","/c","taskkill /f /t /pid " + pid);
Process p1 = pb1.start();

Also, I tried ending process tree implementation with ProcessHandle, but I am facing the same problem.

What doesn't it kill? The process that spawns the cmd prompt? – access violation Nov 08 '22 at 23:43
It does not kill java.exe. – metinbinbir Nov 08 '22 at 23:48
So just exit when the process 'p1' has completed. – access violation Nov 09 '22 at 00:14
Thank you anyway but I realized that the latest java.exe in the tasklist was my java program to kill the process tree. So, I think both ProcessBuilder and ProcessHandle implementations are working. – metinbinbir Nov 11 '22 at 21:22
