IllegalStateException when changing display mode of JFrame

Question

My application has an information console inside a JFrame. The console is continually updating and repainting.
I let the user drag this window wherever they want, resize it how they want, etc. I also give them the ability to select one of three display modes:
- "Decorated Window"
- "Undecorated Maximized Window"
- "Undecorated Fullscreen Exclusive Window"
The toggling between modes normally works well, but occasionally an "IllegalStateException: Buffers have not yet been created" is thrown by (from what I can tell), a component on the console that's trying to be repainted.
Seems obvious to me that something doesn't like the fact that the JFrame has been disposed for an instant and can't deal with it appropriately. Question is, what the hell can I do about it?
I believe everything continues fine despite the exception (although I have a hard time reproducing on my system), but still, it's a wart and I'd like to chop it off.
Here's my code for changing the window mode.
public void setDisplayMode(Component parent,
         ConsoleDisplayMode newDisplayMode) {
     GraphicsDevice device = this.getGraphicsConfiguration().getDevice();
     int state;
     switch (newDisplayMode) {
     case DisplayAsDecoratedWindow:
         // Add the decorations
         this.dispose();
         this.setUndecorated(false);
         this.setVisible(true);
         device.setFullScreenWindow(null);
         // De-iconify
         state = this.getExtendedState();
         state &= ~JFrame.ICONIFIED;
         this.setExtendedState(state);
         // Minimize
         state = this.getExtendedState();
         state &= ~JFrame.MAXIMIZED_BOTH;
         this.setExtendedState(state);
         break;
     case DisplayAsUndecoratedWindow:
         // Remove the decorations
         this.dispose();
         this.setUndecorated(true);
         this.setVisible(true);
         device.setFullScreenWindow(null);
         // Make sure it is de-iconified
         state = this.getExtendedState();
         state &= ~JFrame.ICONIFIED;
         this.setExtendedState(state);
         // Maximize
         state = this.getExtendedState();
         state |= JFrame.MAXIMIZED_BOTH;
         this.setExtendedState(state);
         break;
     case DisplayFullScreenExclusive:
         if (device.isFullScreenSupported()) {
          int choice = JOptionPane
               .showConfirmDialog(
                    parent,
                    "Warning:\n\n"
                         + "This mode is meant for users with a multiple-monitor configuration.\n"
                         + "In this mode, the console controls the graphics device exclusively\n"
                         + "and other windows (such as the other TM windows and dialogs) cannot\n"
                         + "be displayed over the console.\n\n"
                         + "If you have a single monitor, use the mode called\n"
                         + "\""
                         + ConsoleDisplayMode.DisplayAsUndecoratedWindow
                              .toString() + "\".\n\n"
                         + "Continue with this mode?",
                    "Confirm full-screen mode",
                    JOptionPane.YES_NO_OPTION,
                    JOptionPane.WARNING_MESSAGE, ChipIconFactory
                         .getWarningChipIcon());
          if (choice == JOptionPane.YES_OPTION) {
              this.dispose();
              this.setUndecorated(true);
              this.setVisible(true);
              state = this.getExtendedState();
              state &= ~JFrame.ICONIFIED;
              this.setExtendedState(state);
              device.setFullScreenWindow(this);
         } else {
          JOptionPane
               .showMessageDialog(
                    null,
                    "Your graphics device does not support full-screen mode",
                    "Unable to display in full-screen mode",
                    JOptionPane.ERROR_MESSAGE, ChipIconFactory
                         .getErrorChipIcon());
         break;
    }
