Slow startup with launch4j until FlatLaf v1.1

From version 1.1 to 1.1.2, the execution of my newly exe program (converted with launch4j) is very slow.

Here is the code is use to set FlatLaf :

public static void main(String[] args) {
    try {
        UIManager.setLookAndFeel(new FlatDarculaLaf());
    } catch (UnsupportedLookAndFeelException e) {
        e.printstacktrace();
    }
    SwingUtilities.invokeLater(Swappy::createAndShowGUI);
}

But everything is fine with version < 1.1 The thing is, I can’t use embedded menu bar because I am obliged to use version 1.0

PS : this issue appears to only show when I convert my jar file to an exe file with launch4j.
