this one helps. I have a manyToMany relationship between two tables when I write a join query between these two tables, I get an error while loading the project. , Your named query has 2 WHERE keywords in it:
code :
SELECT c
from LicenseComponentDefinition c join c.licenseKeyTypes lkt 
WHERE lkt.keyTypeId = :keyTypeId 
AND WHERE c.product.productId = :productID
AND c.productVersionByVersionStartId.versionId <= :versionId 
AND c.productVersionByVersionEndId.versionId >= :versionId")

it should still fix some issue From the comment of coladict: "UserType implementations are not added to the recognized types you can use in native queries" So the solution was to convert the object to string and cast the string as jsonb.
code :
TestJobRepositoryCustomImpl.java

@Transactional
public class TestJobRepositoryCustomImpl implements TestJobRepositoryCustom {

    @PersistenceContext
    private EntityManager entityManager;

    @Autowired
    private ObjectMapper objectMapper;

    @Override
    public int upsert(UUID id, Parameters parameters) {
        final String parametersAsString = objectMapper.writer().writeValueAsString(parameters);
        final Query query = entityManager.createNativeQuery("INSERT INTO testjob (id, parameters) VALUES(:id, cast(:parameters as jsonb))");
        query.setParameter("id", id);
        query.setParameter("parameters", parametersAsString);
        return query.executeUpdate();
    }

}

Any of those help NamedQuery should be written with JPQL, but query seems to mix both names of persistent attributes and names of database columns. Names of database columns cannot be used in JPQL.
In this case instead of next_fire_time name of the persistent attribute epochTime should be used. Also trigger_name looks more like name of the database column than name of the persistent attribute, but it seems not to be mapped in your current class at all. After it is mapped, query is as follows:
org.hibernate.HibernateException: Not able to obtain connection

org.hibernate.HibernateException: Not able to obtain connection

Hope this helps Manual memory management is not available in Java. The object will automatically become eligible to be recycled when it goes out of scope. What is holding onto your object? There must be a class, or another object referencing it for it not to be recycled by the GC.
