Erro ao Tentar Adicionar método na interface filha de JpaRepository no Spring Data

Assuntos Gerais
#1

Bom dia Companheiros e Companheiras,

Estou batendo cabeça aqui na tentativa de adicionar o Spring Data a um projeto.
Estudei o Spring Data, muito legal, mas na hora de adicioná-lo ao projeto estou tendo problemas, sempre é disparada a exception

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uFRepository': Post-processing of the FactoryBean's object failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class [class $Proxy16]: Common causes of this problem include using a final class or a non-visible class; nested exception is java.lang.IllegalArgumentException: Cannot subclass final class class $Proxy16

O curioso é que o seguinte código funciona perfeitamente:

@Transactional
public interface UFRepository extends JpaRepository<UF, Long> {

   // Sem declarações
}

E este não.

[code]
@Transactional
public interface UFRepository extends JpaRepository<UF, Long> {

 UF findBySigla(String sigla); //Com declaração.

}[/code]

Alguém já teve esse problema? Tem alguma ideia do que pode ser? Já alterei a versão de tudo relacionado no Maven, e depois voltei pra essa versão. O erro é sempre o mesmo. Minhas desconfianças são versões das dependências e o fato de busar 2 persistence Unit.

Desde já agradeço.
Abraço

Reativando o post, alguma consideração sobre o ocorrido com o colega acima? Estou enfrentando o mesmo problema.
