Detect the Windows key modifier

Question

How can I detect the Windows key modifier for KeyEvent? I have add the code:

textField.addKeyListener(new KeyAdapter() {
    public void keyReleased(KeyEvent e) {
        if ((e.getKeyCode() & KeyEvent.VK_ESCAPE) == KeyEvent.VK_ESCAPE) {
            textField.setText("");
        }
    }
});

But the problem is, when I use the Windows zoom and try to exit from it using Win + Escape, if focus is in TextField, its content clears. I've tried filter by e.getModifiersEx(), but it returns 0. The only way I've found is to detect whether Windows pressed or not, is to create boolean field and change it's value when Windows pressed/released.

So, is there any way to get the Windows key pressure state from KeyEvent for ESCAPE released event?

The way I used for myself:

AbstractAction escapeAction = AbstractAction() {
    public void actionPerfomed(ActionEvent e) {
        setText("");
    }
}

textField.addCaretListener(new CaretListener() {
    @Override
    public void caretUpdate(CaretEvent e) {
        if (textField.getText() == null || textField.getText().isEmpty()) {
            textField.getActionMap().remove("escape");
            textField.getInputMap().remove(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0));
        } else {
            textField.getActionMap().put("escape", escapeAction);
            textField.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), escapeAction);
        }
    }
});
