FileDialog does not remember previous directory

[Phillipus]

Windows 10
Eclipse 4.23 and 4.24

This seems to be a regression as this is working in Eclipse 4.22 but not in 4.23 and 4.24.

In the SWT as used in Eclipse 4.22 and earlier, a FileDialog would remember the last open directory. In the SWT in Eclipse 4.23 and later it reverts to the root "Computer" directory on Windows.

Run the snippet below against a target of Eclipse 4.22 and compare with a target of 4.23. Click the "Open" button, navigate to a file and open this. Repeat. On Eclipse 4.22 target the previous directory is remembered. Not on 4.23 target.

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.FileDialog;
import org.eclipse.swt.widgets.Shell;

public class FileOpen {

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setLayout(new GridLayout());
        shell.setSize(300, 200);
        
        Button button = new Button(shell, SWT.PUSH);
        button.setText("Open");
        button.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {
                new FileDialog(shell, SWT.OPEN).open();
            }
        });
        
        shell.open();

        while(!shell.isDisposed()) {
            if(!display.readAndDispatch()) display.sleep();
        }
        display.dispose();
    }
}

Just discovered a workaround:

FileDialog.setFilterPath(null);
