Peguei o pom.xml do projeto do curso no final do capítulo 5, que estava diferente do meu, baixei as dependências e nada.

Consegui resolver o meu problema. O console estava me exibindo a exceção errada. Daí peguei a estrutura do método write em FileSaver do projeto disponibilizado no final do cap. 5 e ao tentar salvar, me lançou uma exceção indicando que o arquivo já existia no diretório onde eu estava tentando salvar.

Método antigo, escrito por mim junto com o Cap. 5

    public String write(Part part, String path) {
        String relativePath = path + "/" + part.getSubmittedFileName();
        try {
            part.write( SERVERPATH + "/" + relativePath);

            return relativePath;
        } catch(IOException e){
            throw new RuntimeException();
        }
    }

Método do projeto disponibilizado no final do Cap. 5

    public String write(Part arquivo, String path) {

        String relativePath = path + "/" + arquivo.getSubmittedFileName();
        String fullPath = SERVERPATH + "/" + relativePath;
        try {
            arquivo.write(fullPath);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

        return relativePath;        
    }

A diferença mais significativa é que o return do método está fora do try.
