title: What could be reason for "Prism-ES2 Error : GL_VERSION (major.minor) = 1.4"?
body: <p>I am trying to develop simple javafx programs in Oracle Linux using eclipse IDE.
  i have installed jdk 7 and all programs runs properly except it shows </p>
  
  <pre><code>Prism-ES2 Error : GL_VERSION (major.minor) = 1.4
  </code></pre>
  
  <p>in console.</p>
  
  <p>For example,Following is the simple javaFX program</p>
  
  <pre><code>import javafx.application.*;
  import javafx.scene.Group;
  import javafx.scene.Parent;
  import javafx.scene.Scene;
  import javafx.scene.paint.Paint;
  import javafx.stage.Stage;
  public class practiceFX extends Application{
  public static void main(String args[])
  {
      Application.launch(args);
  }
  
  @Override
  public void start(Stage primaryStage) throws Exception {
      // TODO Auto-generated method stub
      Group root =new Group();
      Scene scene =new Scene(root,200,300);
      primaryStage.setTitle("PRACTICE");
      primaryStage.setScene(scene);
      primaryStage.setResizable(true);
      primaryStage.setScene(scene);
      primaryStage.show();
      System.out.println("hi");
  
  }
  }
  </code></pre>
  
  <p>and the output is</p>
  
  <pre><code>Prism-ES2 Error : GL_VERSION (major.minor) = 1.4
  hi
  </code></pre>
  
  <p>Please see the screenshot too
  Also I can not run the javaFX samples.
  When i am trying to run Ensemble.jar then it shows following error</p>
  
  <pre><code>Prism-ES2 Error : GL_VERSION (major.minor) = 1.4
  
  GThread-ERROR **: GThread system may only be initialized once.
  aborting...
  Aborted (core dumped)
  </code></pre>
