After #7088744 was fixed 3 JCK tests started to fail.

The following mini test reproduces the unexpected behavior:

import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseEvent;

public class Test {

    public static void main(String[] args) throws Exception {

        Component comp = new Canvas();
        MouseEvent event = new MouseEvent(comp, 0, 0, MouseEvent.BUTTON1_MASK,
                0, 0, 0, false);

        if (SwingUtilities.isLeftMouseButton(event)) {
            System.out.println("OK");
        } else {
            System.out.println("Failed. Reported as not left mouse button");
        }
    }
}
