New to Java

I thought my method would handle this dynamically, but I was way off:

       /**
         * Handle {@link javax.swing.JButton}
         * @param button {@link javax.swing.JButton}
         */
        private void handleButton(JButton button) {
            try {
                String text = button.getText();
                ImageIcon icon = new ImageIcon(
                        System.getProperty("com.ppowell.applications.globals.rockpaperscissorsglobals.SRC_PATH") +
                        FileFunctionality.buildFilePath(RockPaperScissorsGlobals.IMAGE_PATH_ARRAY, true) /* EXCLUDE 1 BACKSLASH */ +
                        File.separator +
                        button.getText().toLowerCase().trim() + ".ico");
                button = new JButton(text, icon);
                Dimension dim = new Dimension(icon.getIconWidth(), icon.getIconHeight());
                button.setSize(dim);
                button.setPreferredSize(dim);
                button.setMaximumSize(dim);
            } catch (Exception e) {
                e.printStackTrace();
            }
            button.setFocusable(false);
            button.setSelected(false);
            button.addActionListener(RockPaperScissors.this);
            button.setMnemonic(button.getText().charAt(0));
            button.setFont(RockPaperScissorsGlobals.FONT);
        }

Instead I see JButtons with no icons, looking dead normal, and worse, setFocusable(false) is ignored; the JButtons look like they've been clicked!

What did I do so wrong this time?
Thanx
