title: JDK 8 update 66 fatal error for JavaFx application on Windows 10
body: <p>I'm making a JavaFx app. Today I integrated a login panel and a registration panel to it. After integrating those, I started getting a fatal error whenever I ran the app which didn't happen earlier. The log of the error is as follows:</p>
  
  <blockquote>
    <p>A fatal error has been detected by the Java Runtime Environment:</p>

  <hr>
  
  <p>I also ran the app on a system with <em>Ubuntu 14.04</em> 64 bit (<em>JDK 8u77</em> and <em>Netbeans 8.0.2</em>) and the <strong>app ran fine</strong> without any fatal errors (or any errors).</p>
  
  <p>The thing that I want to know is that, is it a development issue or a JVM issue? Should I just raise an issue and continue with JDK 8u77?</p>
