Spring SpEL JPA @Query - getting "QueryException: Not all named parameters have been set" with numeric column

I've a simple Person entity with two fields:

@Entity
@Table(name = "person")
public class Person implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "name", length = 50)
    private String name;

    //setter/getters
}

A JpaRepository where I override the findAll method to restrict the records based on user role:

public interface PersonRepository extends JpaRepository<Person,Long> {

    @Query("select p from Person p where p.name like ?#{hasRole('ROLE_ADMIN') ? '%' : principal.username}")
    @Override
    List<Person> findAll();
}

The above setup is working fine. But when I update the query to be the following, it throws me exception as below. It looks it failed to parse the SpEL expression.

Problematic query:

@Query("select p from Person p where p.id like ?#{hasRole('ROLE_ADMIN') ? '%' : principal.userId}")

Exception:

I played around it and tried the following options, but got the same exception:

1) replacing LIKE with =

@Query("select p from Person p where p.id = ?#{hasRole('ROLE_ADMIN') ? '1' : principal.userId}")

2) Setting hard coded ids :

@Query("select p from Person p where p.id = ?#{hasRole('ROLE_ADMIN') ? '6' : '5'}")

Any suggestions?

FYI :

• I've spring boot 1.3.6.RELEASE, hibernate 4.3.11.Final in my pom.xml.
• I've correctly configured/overridden the org.springframework.security.core.userdetails.User object to pass the userId.
