      Description

      FULL PRODUCT VERSION :
      java version "1.8.0"
      Java(TM) SE Runtime Environment (build 1.8.0-b132)
      Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      When using Calibri font in 12pt bold, the - sign is not rendered with the default antialiasing mode.

      When using RenderingHints.VALUE_TEXT_ANTIALIAS_LCD_HRGB oder RenderingHints.VALUE_TEXT_ANTIALIAS_LCD_HBGR the - is not visible.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Just run the code example below. Setting the Fomnt to Calibi, bold, 12, and then using RenderingHints.VALUE_TEXT_ANTIALIAS_LCD_HRGB reproduces the problem.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The expected result when running the code above is to see three times -100.
      ACTUAL -
      The -100 rendered with enderingHints.VALUE_TEXT_ANTIALIAS_LCD_HRGB is displayed as 100.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      public static void main(String[] args) {

      SwingUtilities.invokeLater(new Runnable() {

      @Override
      public void run() {

      final Font f = new Font("Calibri", Font.BOLD, 12);
      final String str = "-100";

      JTextField tf = new JTextField(9);
      tf.setFont(f);
      tf.setText(str);

      @SuppressWarnings("serial")
      JPanel panel = new JPanel() {
      protected void paintComponent(java.awt.Graphics g) {
      super.paintComponent(g);

      g.setFont(f);
      g.drawString(str, 3, 15);

      ((Graphics2D)g).setRenderingHint(
      RenderingHints.KEY_TEXT_ANTIALIASING,
      RenderingHints.VALUE_TEXT_ANTIALIAS_LCD_HRGB);
      g.drawString(str, 3, 35);

      ((Graphics2D)g).setRenderingHint(
      RenderingHints.KEY_TEXT_ANTIALIASING,
      RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT);
      g.drawString(str, 3, 45);

      };
      };
      panel.setPreferredSize(new Dimension(30, 50));
      panel.setBackground(Color.WHITE);

      JFrame frame = new JFrame();
      frame.setSize(300, 200);
      frame.setLocationRelativeTo(null);
      frame.setLayout(new FlowLayout());
      frame.add(tf);
      frame.add(panel);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setVisible(true);
      }
      });
      }
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Setting a different Antialiasing Rendering Hint helps, but you must do it in every paint method.
