Hello,

Below is the error demonstration.

In JForex I open three almost identical simple strategies:
package jforex;
 
import com.dukascopy.api.*;
import javax.swing.*;

public class XXXX implements IStrategy {
    private IUserInterface userInterface = null;
   private final String tabName = "XXXX tab";
 
    @Override
    public void onStart(IContext context) throws JFException {
        this.userInterface = context.getUserInterface();
        JPanel tab = userInterface.getBottomTab(tabName);
    }
 
    @Override
    public void onTick(Instrument instrument, ITick tick) throws JFException {}
 
    @Override
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {}
 
    @Override
    public void onMessage(IMessage message) throws JFException {}
 
    @Override
    public void onAccount(IAccount account) throws JFException {}
 
    @Override
    public void onStop() throws JFException {
        if (userInterface != null) {
            userInterface.removeBottomTab(tabName);
        }
    }
}

The only one difference between strategies is XXXX replaced by YYYY and ZZZZ consequently (all files attached).

I do the following steps:
  1. in the "Strategies" tab I select all three strategies,
  2. in the "Strategies" tab I press "start" button once,
  3. I close log tabs for all strategies (i.e. tabs named "XXXX", "YYYY", "ZZZZ" and eventually ""). I close those tabs because (1) I don’t need them, (2) those tabs take place on my dashboard and (3) change its layout,
  4. in "Strategies" tab I press "stop" button,
  5. in "Strategies" tab I press "start" button again,
  6. I do repeat aforementioned steps 3-5 until an error occurs (usually 1-3 times).

As a result the following error occurs:
