Entity class:

@Table(name = "human_table")
class HumanEntity(

Repository methods with HQL:
{noformat}interface HumanEntityRepository : JpaRepository<HumanEntity, Int> {
@Query("select he from HumanEntity he where :names is null or he.name in :names ")
fun findByNames(names: List<String>?): List<HumanEntity>
@Query("select he from HumanEntity he where :genders is null or he.gender in :genders ")
fun findByGender(genders: List<Gender>?): List<HumanEntity>

{noformat}
Calling {{humanEntityRepository.findByGender(listOf(Gender.MALE, Gender.FEMALE))}} produces
{noformat}java.lang.ClassCastException: class java.util.Arrays$ArrayList cannot be cast to class java.lang.Enum (java.util.Arrays$ArrayList and java.lang.Enum are in module java.base of loader 'bootstrap')
