JFileChooserFixture.selectFile() fails if called twice in OSX

Start by reproducing the supplied FileChooserTest on macOS, especially the second call to selectFile(), then inspect JFileChooserFixture.selectFile() and the related file-chooser fixture tests. Done means the same file can be selected and approved successfully on the second invocation as well as the first, without breaking Windows behavior.

Hi,

The following second Test fails on OSX. On Windows it works like expected. It might be a Swing issue in the MAC VM.

public class FileChooserTest extends AssertJSwingJUnitTestCase {

    protected FrameFixture window;
    protected Robot robot;

    @Override
    protected void onSetUp() {

        FileChooserFrame mainFrame = GuiActionRunner
                .execute(new GuiQuery<FileChooserFrame>() {

                    protected FileChooserFrame executeInEDT() {

                        return new FileChooserFrame();
                    }
                });
        robot = robot();
        window = new FrameFixture(robot, mainFrame);
    }

    @Test
    public void openFileChooser() {
        selectFile();

    }

    @Test
    public void openFileChooserAgain() {
        selectFile();
    }

    private void selectFile() {
        String seperator = System.getProperty("file.separator");
        String currentDir = new File("").getAbsolutePath() + seperator + "src";
        String filePath = currentDir + seperator + "FileChooserFrame.java";

        window.button().click();
        JFileChooserFixture fileChooser = JFileChooserFinder.findFileChooser()
                .using(robot);

        fileChooser.setCurrentDirectory(new File(currentDir));
        fileChooser.selectFile(new File(filePath));
        fileChooser.approve();

        window.textBox().requireText(filePath);
    }

}
