b10: regression?

[Florian Brunner]

Hi,

On Linux (32-bit) with JavaFX 2.2 b08 I was able to instantiate a control in a unit test, e.g.

import javafx.scene.control.CheckBox;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;


public class MyTest {
    
    public MyTest() {
    }

    
    @Before
    public void setUp() {
        CheckBox cb = new CheckBox("test");
    }
    
    @After
    public void tearDown() {
    }


    @Test
    public void someTest() {
        System.out.println("someTest");
    }

}

With b10 I'm getting an error:

Is this a regression or a desired behaviour? If it's a desired behaviour: Is there a way to write some simple JUnit tests for controls?
