Pessoal, bom dia.

A meses estou tentando desvendar este problema, porém sem solução, gostaria, se possível, uma ajuda neste problema. Segue abaixo o problema:

Erro: Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: cannot assign instance of net.sf.jasperreports.engine.base.JRBaseStyle to field net.sf.jasperreports.engine.base.JRBaseParagraph.paragraphContainer of type net.sf.jasperreports.engine.JRParagraphContainer in instance of net.sf.jasperreports.engine.base.JRBaseParagraph

Segue também o código que utilizo para chamar o arquivo Jasper:

  
    Connection conn = ConnectionFactory.getConnection();
    
    String src = "C:/relatorios/rplorcamento/clientes.jasper";
    
    JasperPrint jaspertPrint = null;
    
    try {
        
        jaspertPrint = JasperFillManager.fillReport(src, null, conn);
        
    } catch (JRException ex) {
        System.out.println("Error: "+ex);
    }
    
    JasperViewer view = new JasperViewer(jaspertPrint,false);
    
    view.setVisible(true);

Desde já ficarei no aguardo de uma posição,

Att,
