Yes, that is the program I used, and yes, I get the 'Toolkit not initialized' exception. I am running IntelliJ, so that is the reason. I switched over to Eclipse and the code run as expected.

I am slightly bothered by the occasional failures that seem to be IntelliJ-specific. I have a gut feeling that it doesn't always run all tests (or that it runs them slightly differently to get different results than when run on the command line). Does anyone know why this is?

I'm actually most at home in Eclipse, so perhaps I should switch to that as my primary IDE for OpenJFX development.

Just to make sure we are running the same program, the one I ran to verify that RT-33954 is fixed was the simple test program in the comments of that bug. Here it is (with the imports omitted for brevity).

public class Example extends Application {
   public static void main(String[] args) {
//this is called from a static block in javafx.scene.control.Control


   public void start(final Stage primaryStage) throws Exception {

The above program runs fine for me with no exception.

Jonathan: are you seeing something different? Or perhaps running a different example?

NOTE: if you run this from IntelliJ it will not work. I verified that with Debbie last week (on a different issue), which may be why you are seeing a problem. Running it from command line, from NB, or from Eclipse works.

Firstly, I agree - this does seem to still be reproducible despite Kevin's comment that it should have been resolved in JavaFX 8.0 due to RT-28754 <>, so that is troubling. I'll leave Kevin to comment on that.

Secondly, RT-33954 was closed as a duplicate of RT-28754 <>, so it would be better to leave RT-33954 closed and move discussion (including what you recently posted) into RT-28754 <>. The discussion can start in there and most probably a new bug will need to be opened (as RT-28754 <> did result in a code change that at one point appears to have fixed the problem, so we're possibly dealing with a regression).

Thirdly, whether this is a suitable bug for someone learning the ropes is debatable. I'll leave Kevin to offer his thoughts, but perhaps you can propose a patch that resolves this issue for you in your test scenarios. Also, a good starting point is to develop a simple test application that helps to demonstrate this issue (preferably the test case is a single class with no dependencies), and which you can then share in the jira issue via copy/paste into a comment.

Fourthly, to be a contributor in the OpenJDK requires you to follow a process to get the paperwork in order. It is wise to get that started as soon as possible, as it can sometimes take a while. Here's a link to the process: The main thing is the OCA.

Finally, welcome! :-)

Hi JavaFX devs!

I was wondering how people felt about re-opening this bug? I don't believe
it has been fixed (see my comment).

I'm also happy to work on it. But, let me know if you think my time would be better spent elsewhere. I'm keen to take on a small bug to just get the hang of the process and community (I'll be stumbling with mercurial along
the way too!). I think this bug is an ideal candidate for someone just
learning the ropes.
