Why is my JPA derived query case insensitive by default? - jpa

Question

All materials I have read so far indicate that case sensitive is the default behavior for a JPA query, and you need to add IgnoreCase to add that feature to the query. However, when I run my findByName(String name) derived query, it is able to identify the "checking" and "savings" accounts without case. Do I have something setup that would cause this? How can I switch to case sensitive?
#Entity
#Table(name = "gl_account")
public class Account extends Entry {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Integer id;
#Column(name = "number", unique = true, nullable = false)
#NotBlank
private String number;
#Column(name = "name", unique = true, nullable = false)
#NotBlank
private String name;
#ManyToOne(fetch = FetchType.LAZY, optional = false)
#JoinColumn(
name = "element_id",
referencedColumnName = "id",
foreignKey = #ForeignKey(name = "fk__gl_account__element_id"),
nullable = false
)
#NotNull
private Element element;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(
name = "player_id",
referencedColumnName = "id",
foreignKey = #ForeignKey(name = "fk__gl_account__player_id")
)
private Player player;
// constructors, setters, getters, equals, hashcode
}
#Repository
public interface AccountRepository extends PagingAndSortingRepository<Account,Integer> {
Optional<Account> findByName(String name);
}
#Service
public class AccountService {
private final AccountRepository REPO;
#Autowired
public AccountService(AccountRepository repo) {
REPO = repo;
}
public Account findByName(String name) {
return REPO.findByName(name).orElse(null);
}
}

public void findByName_test1(String name) {
Account account = svc.findByName(name);
assertNotNull(account);
}
INSERT INTO gl_account
(number, name, element_id, player_id)
VALUES

There are databases that compare case insensitive by default.
