One possible option: https://www.b4x.com/android/forum/threads/killing-forgotten-java-processes.82584/#content

Another option is to add a "kill" server handler and then call it from a browser.

Example from B4i builder:
B4X: 
Sub Class_Globals
    Private t1 As Timer
End Sub

Public Sub Initialize
    
End Sub

Sub Handle(req As ServletRequest, resp As ServletResponse)
    resp.Write("Killing server...")
    t1.Initialize("t1", 100)
    t1.Enabled = True
    Log("Killing server...")
End Sub

Sub t1_tick
    ExitApplication
End Sub

You can also try this, which is based on Erel's first suggestion:

Managing Hidden Jar Processes

Based on Erel's tutorial here: https://www.b4x.com/android/forum/threads/killing-forgotten-java-processes.82584/#content I made this program mainly to view and kill Jar processes that are hidden (non - UI) Of course, the TableView shows both UI and non UI Jar processes. Note that you might...

Standalone EXE file generation is only supported for UI applications. Non-UI applications (such as jRDC2) are not.

What is jar manager?
Find the process name in task manager and kill it with: https://www.windows-commandline.com/taskkill-kill-process/

JarManager is the app name of my snippet to view and kill hidden java processes.
So, if I understand correctly, my snippet runs OK from the IDE, but not when it has been packaged to exe.
This problem should probably be posted on a different thread, as it has nothing to do with this thread's content.
For the record, I just did a check on my PC and JarManager runs fine on OpenJDK11, packaged wirh B4JPackager11 (standalone).

This might help if I've understood the question....
As an alternative to finding and using PID to terminate,
I use this in a batch file when I run the development server on local machine...kills everything with 'jRDC.jar' in the name.
Stop_jRDC_Process.bat: 
cmd /k wmic path win32_process Where "CommandLine like '%%jRDC.jar%%'" Call Terminate
sleep 2
