EmptyStackException on Linux

[Ted Reynolds]

I have some code that runs great on windows but when I try it on Linux (RH7.0) I get an EmptyStackException. Can anyone help?

Following is some snippets from the offending code.

 here's where I instantiate the dialog.
. . .
case 14:
   if (mode<4)
   {
      String message=action.substring(action.indexOf("message=")+9,action.lastIndexOf("\""));
      panels.add(new ShowMessage(this,message));
   }
   else
   {
      panels.add(new BasePanel(this));
   }
   break;
. . .
 
here's the constructor of the class that this calls
 
public ShowMessage(Frame parent, String message)
{
   super(parent);
   header.setText("Important Message");
   qi=(QuickiInstall)parent;
   /*Set up the GUI of this dialog
   ...
   */
}
 
here's the dialogs parent class
 
public class BasePanel extends JDialog implements ActionListener
{
   public BasePanel()
   {
   }

   public BasePanel(Frame parent)
   {
      super(parent,true);
      qi=(QuickiInstall)parent;
      pwidth=Integer.parseInt(qi.resolveVariables("${PanelSizeX}"));
      pheight=Integer.parseInt(qi.resolveVariables("${PanelSizeY}"));
      setSize(pwidth,pheight);
      setResizable(false);
      setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
      /*More Setup code goes here
      . . . 
      */
   }

   public void actionPerformed(ActionEvent aevt)
   {
      buttonPressed=aevt.getActionCommand();
      hide();
   }
}
 

What am I doing wrong?
