      Description

      The following code produces a NullPointerException, as soon as you click into the TextArea.
      It is caused by the bidirectional binding to a null value, but it's only reproducible with TextArea, not with TextField.


      import javafx.application.Application;
      import javafx.beans.property.SimpleStringProperty;
      import javafx.scene.Scene;
      import javafx.scene.control.TextArea;
      import javafx.scene.control.TextField;
      import javafx.stage.Stage;

      public class TestApp2 extends Application {

          public static void main(String[] args) {
              launch(args);
          }

          @Override
          public void start(final Stage stage) throws Exception {

              TextArea textArea = new TextArea();
              textArea.textProperty().bindBidirectional(new SimpleStringProperty());
              Scene scene = new Scene(textArea);
              stage.setScene(scene);
              stage.show();
          }
      }
