Problemas com JInternalFrame & GRFinger Java SDK

#1

Bom dia pessoal, estou desenvolvendo um aplicativo que tem como principal função a autenticação por meio de impressão digital.
Quando fui testar métodos criados para mostrar a imagem capturada em um JPanel tive alguns problemas com o JInternal frame que executa esses métodos, abaixo segue o erro que o Netbeans me retorna.

Exception occurred during event dispatching:

CONSTRUÍDO COM SUCESSO (tempo total: 23 segundos)

O método que uso drawImage é este:

    private JComponent criarPanelDigital(){
        fingerprintViewPanel = new JPanel(){
            public void paintComponent(Graphics g){
                super.paintComponent(g);
                if(fingerprintImage != null){
                    Insets insets = getInsets();
                    int transX = insets.left;
                    int transY = insets.top;
                    int width = getWidth() - getInsets().right - getInsets().left;
                    int height = getHeight() - getInsets().bottom - getInsets().top;

                    g.drawImage(fingerprintImage, transX, transY, width, height, null);
                }
            }
        };
        fingerprintViewPanel.setBorder(new CompoundBorder(
                new EmptyBorder(2, 2, 2, 2),
                new BevelBorder(BevelBorder.LOWERED)));
        if(fingerprintViewPanel == null){
            return null;
        }else{
                return fingerprintViewPanel;
        }
    }

Alguém sabe o que pode ser ?
