JAVAFX Tableview hangs while resizing application with JAVA RESULT 255 - javafx-2

Question

I have simple javafx application that hangs when resizing.
Application was compiled/build with jdk1.7.0_10
OS: Windows 8
IDE: NetBeans 7.2.1
The problem occurs when I populate bottom table and start resizing by shifting the right border of application. Sometimes I need to play with resizing for a while, shifting inner borders of SplitPanes and external application borders till it collapses. When the row is empty, that is nothing is populated in the table, then everything works fine - no hangings, I can resize in every direction whatever I want - and nothing hangs.
Application hangs and ends with Java Result: 255 in Netbeans Output Window.
What could it be? There are no logs, exceptions, nothing...it drives me mad, lost so much time on it :(
Here is my controller:
public class MyFXMLController implements Initializable {
#FXML
TableView<Person> table;
#FXML
TableColumn<Person, String> firstNameCol;
#FXML
TableColumn<Person, String> lastNameCol;
#FXML
TableColumn<Person, String> carCol;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
firstNameCol.setCellValueFactory(new PropertyValueFactory("firstName"));
lastNameCol.setCellValueFactory(new PropertyValueFactory("lastName"));
carCol.setCellValueFactory(new PropertyValueFactory("car"));
Person p1 = new Person();
p1.setFirstName("A");
p1.setLastName("B");
p1.setCar("ferrari");
ObservableList<Person> teamMembers = FXCollections.observableArrayList(p1);
table.setItems(teamMembers);
}
}
Main class is:
public class TestTableView extends Application {
#Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
}
});
AnchorPane page = null;
try {
page = (AnchorPane) FXMLLoader.load(TestTableView.class.getResource("/testtableview/myFXML.fxml"));
} catch (IOException ex) {
Logger.getLogger(TestTableView.class.getName()).log(Level.SEVERE, null, ex);
}
Scene scene = new Scene(page);
primaryStage.setScene(scene);
primaryStage.setTitle("my");
primaryStage.show();
}

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

And underlying data class is:
package testtableview;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Person {
private StringProperty firstName;
public void setFirstName(String value) {
firstNameProperty().set(value);
}
public String getFirstName() {
return firstNameProperty().get();
}
public StringProperty firstNameProperty() {
if (firstName == null) {
firstName = new SimpleStringProperty(this, "firstName");
}
return firstName;
}
private StringProperty lastName;
public void setLastName(String value) {
lastNameProperty().set(value);
}
public String getLastName() {
return lastNameProperty().get();
}
public StringProperty lastNameProperty() {
if (lastName == null) {
lastName = new SimpleStringProperty(this, "lastName");
}
return lastName;
}
private StringProperty car;
public void setCar(String value) {
carProperty().set(value);
}
public String getCar() {
return carProperty().get();
}
public StringProperty carProperty() {
if (car == null) {
car = new SimpleStringProperty(this, "car");
}
return car;
}
}

However I am not able to see any specific problem here. but it might be problem with your memory management. try to make data class static as a subclass in controller class.
