I'm searching for good solutions about to handle business exceptions inside of activiti process.

I noticed that, any exception throws inside the process execution is encapsulated as ActivitiException.

For example:

1- Process definition:

    <process id="processParametro">
        <startEvent id="iniciarProcessoParametro"/>
        <sequenceFlow sourceRef="iniciarProcessoParametro" targetRef="criarParametro"/>
        <serviceTask id="criarParametro"
                     name="Incluir Parametro"
                     activiti:expression="${parametroService.create(nomeParametro, descricaoParametro)}"
        <sequenceFlow sourceRef="criarParametro" targetRef="finalizarProcessoParametro"/>
        <endEvent id="finalizarProcessoParametro"/>

2- The method create inside ParametroService class:

    @Transactional(readOnly = false)
    public Parametro create(String nome, String descricao) {
        Parametro parametro = parametroRepository.findByNome(nome);
        if (parametro != null){
            throw new BusinessException("");
        Parametro parametro = new Parametro(nome, descricao, SituacaoParametroEnum.PENDENTE_ATIVACAO.asDomain());

If the method parametroRepository.findByNome(nome) return a parametro = null, the BusinessException will be thrown. But, the exception I'm receving in my client is ActivitiException.
I'm thinking to get a BusinessException inside the ActivitiException, but I think it isn't  a good design.

Someone has a better solution?
