Is it a JTextPane's bug?

Question

I wrote some test code as below:
public class TTextComponents {
     public static void main(String[] args) {
//          final JEditorPane editorPane = new JEditorPane();
          final JTextPane textPane = new JTextPane();
          final JButton btn = new JButton("open");
          btn.addActionListener(new ActionListener()
                         /* (non-Javadoc)
                          * @see java.awt.event.ActionListener#actionPerformed(java.awt.event.ActionEvent)
                         public void actionPerformed(ActionEvent e) {
                              JFileChooser fc = new JFileChooser();
                              int ret =fc.showOpenDialog(btn);
                              if(ret == JFileChooser.APPROVE_OPTION)
                                   try {
//                                        editorPane.setPage(fc.getSelectedFile().toURL());
                                        textPane.setPage(fc.getSelectedFile().toURL());
//                                        printEditorPane(editorPane);
                                        printEditorPane(textPane);
                                   } catch (MalformedURLException e1) {
                                        // TODO Auto-generated catch block
                                        e1.printStackTrace();
                                   } catch (IOException e1) {
                                        // TODO Auto-generated catch block
                                        e1.printStackTrace();
//          printEditorPane(editorPane);
          printEditorPane(textPane);
          JPanel mainPane = new JPanel(new GridLayout(1,2));
//          mainPane.add(editorPane);
          mainPane.add(textPane);
          JFrame frame = new JFrame("JFrame Test!");
          Container c = frame.getContentPane();
          c.setLayout(new BorderLayout());
          c.add(btn,BorderLayout.NORTH);
          c.add(mainPane,BorderLayout.CENTER);
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.pack();
          frame.setVisible(true);
          printEditorPane(textPane);
     private static void printEditorPane(JEditorPane pane)
          System.out.println(pane +" is:");
          System.out.println("model is: "+pane.getDocument());
          System.out.println("editorkit is: "+pane.getEditorKit());
          System.out.println("content type is: "+pane.getContentType());
          System.out.println("\n");
}now i use the button to open a non- plaintext file firstly, then open a plain-text, IllegalArgumentException was thrown.
I debug into the code, found if content-type was changed, JTextPane use javax.swing.JEditorPane$PlainEditorKit as plaintext's EditorKit, but it only accept StyledEditorKit.

Hi Gowri,
We have also faced the same issue. for the data we are showing in measure tab in pivot table changed into Show Data as -> Percentage of -> Column is showing correct percentage data in pivot table. But if we are taking 'chart Pivoted Results' the chart is showing only the value not percentage.
Result: Only '*Pie*' chart work with solution and show same percentage in the pie chart view. In bar, line and other chart results will not display the expected result.
Hope it helps.
