With the use of national symbols in ExtensionFilter JVM crashes immediately.

{code}
public class Proof extends Application
{
public static void main (String[] args)
{
Application.launch(args);
}

@Override
public void start (Stage primaryStage) throws Exception
{
FileChooser fileChooser = new FileChooser();
fileChooser.getExtensionFilters().add(new FileChooser.ExtensionFilter("Файл XML", "*.xml"));
fileChooser.showOpenDialog(primaryStage);
}
}
{code}
