You must update the UI elements on the UI thread using Platform.runLater().

If you have a long-running task, then perform the task first, and the update the UI with the results of the task.

Object taskResult = GetLongRunningTaskResult();
Platform.runLater(() -> Pane.getChildren().add(taskResult));
