JPA backslash/escape double quote regression in 2.6.5

[brandonfl]

Hello,

Previous Spring boot version : 2.6.4
New Spring version : 2.6.5
Dependency : spring-boot-starter-data-jpa

When trying to update Spring Boot I get this new erreor :

org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [\] did not match expected type [java.lang.String (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [\] did not match expected type [java.lang.String (n/a)]

It's currently not possible to use \" into JPA. As for example :

List<TestEntity> testEntities = testRepository
        .findAllByJsonNameContaining("\"fr\":\"test\"");

For more info, here is the repository :

public interface TestRepository extends JpaRepository<TestEntity, Long>,
        JpaSpecificationExecutor<TestEntity> {

    List<TestEntity> findAllByJsonNameContaining(String jsonName);
}

I also tryed with multiple backslash as \\\" but I still have the same error...

Thanks in advance for the response 😄
