title: Why would scenebuilder 2.0 fail to open my fxml file?
body: <p>I have an fxml file that I created using SceneBuilder 2.0. This file is used in my JavaFx project that I am developing using Netbeans 8. Today, SceneBuilder stopped working with my file. When I tried to open it, SceneBuilder would minimize and would not open the file. I don't have any custom components in my scene graph. </p>
  
  <p>I copied the contents of the file into a new fxml file and gave it a new name. SceneBuilder was then able to open this file even though the contents are identical to the file that it is unable to open. </p>
  
  <p>What is going on here? </p>
  
  <p>my apologies, but I am unable to post the contents of the fxml file. </p>
