Como implementar "Verificar paramentros pelo ManageBean e redirecionando para outra parte"?

É o seguinte pessoal queria que minha aplicação ao ser aberta verificasse a data que expira a licença da mesma.
Tentei da seguinte maneira. Ao efetuar login ele verificasse as datas caso a expireDate for posterior a data de hoje ele redirecionaria para uma pagina de erro onde ele poderia colocar uma nova chave.

Metodo que verica as datas dentro do manageBean:

public final boolean isExpirated() throws ParseException, IOException{
        Date date1 = null;
        Date date2 = null;
        
        List<Empresa> result = empresaRepository.find();
        //SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");  
        //Date expiraDate = format.parse(result.get(0).getExpireDate().toString());  
        Date expireDate = result.get(0).getExpireDate();  
        if (expireDate.after(new Date())) {  
            setLiberado(false);
            System.out.println(" Ainda vai acontecer o dia");
            
        } else if (expireDate.before(new Date())) {  
            setLiberado(true);
            //
            System.out.println(" O dia já aconteceu");
            
        }  
        
        return isLiberado();
    }

e dentro do contrutor coloquei da sequinte maneira:

public licencaBean() throws ParseException, IOException  {
        System.out.println("Preparando para acessar o metodo");
        if (isExpirated()){
            FacesContext.getCurrentInstance().getExternalContext().redirect("licenca.faces");
            
        }
        System.out.println("O metodo foi acessado");
        
    }

so que ocorre o erro

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘licencaBean’ defined in file

ficaria muito grato se alguem pudesse me ajudar com esse problema ou me indicasse um outra solução

Veja que o stackTrace indica que há um NullPointerException no construtor.
Ele aponta a linha onde a falha ocorre.
Dê uma olhada com mais atenção.

Consegui resolver o problema do construtor com @PostConstruct no metodo;

Mas agora tenho um outro problema, preciso matar a sessão.
Tentei da seguinte maneira criei o metodo destroySession.

private void destroySession() {
        SecurityContextHolder.clearContext();
        
 }

Aparentemente funciona normal mas há uma brecha esse MB esta linkado a pagina Home.faces (onde é redirecionado apos o login) se acesso outra pagina diretamente o spring Security manda ele pra pagina de login e apos efetuar o login e passa normal. Precisa linkar esse MB ao login mas este usa Spring Security que não sei como alterar;

O metodo que faz o teste se expirou ou não a data de licença e este

@PostConstruct      
    private void isExpirated(){
        String expirado = null;
        if (this.getEmpresa().getExpireDate() == null){
            destroySession();
            try {
                FacesContext.getCurrentInstance().getExternalContext().redirect("wizardInstalation.faces");
            } catch (IOException ex) {
                Logger.getLogger(LicencaBean.class.getName()).log(Level.SEVERE, null, ex);
            }
        }else{
            expireDate = getEmpresa().getExpireDate();
            destroySession();
                if (expireDate.before(new Date()) || (!getEmpresa().getAtivo())) {  
                    if (this.getEmpresa().getCodCliente()==null){
                        setRegistrado(false);
                        setTitulo("Seu periodo de experiência acabou!!!");
                    }else{
                        
                        setRegistrado(true);
                        setTitulo("Sua chave expirou!!!");
                    }
                    getEmpresa().setAtivo(false);
                    empresaRepository.merge(getEmpresa());
                    try {
                        FacesContext.getCurrentInstance().getExternalContext().redirect("licenca.faces");
                    } catch (IOException ex) {
