If the parameter is correctly typed it works. For the Object type Parameter, querying for a simple value like a string also works. final CriteriaBuilder cb = entityManager.getCriteriaBuilder(); final CriteriaQuery<WithEmbedded> query = cb.createQuery(WithEmbedded.class); final Root<WithEmbedded> root = query.from(WithEmbedded.class); //deliberately using Object type here, using AnEmbeddable works final ParameterExpression< Object > parameter = cb.parameter( Object.class); query.select(root).where(cb.equal(root.get( "e" ), parameter)); final TypedQuery<WithEmbedded> typedQuery = entityManager.createQuery(query); typedQuery.setParameter(parameter, new AnEmbeddable( "a" , "b" )); typedQuery.getResultList(); // throws AssertionError java.lang.AssertionError at org.hibernate.query.sqm.internal.SqmUtil.createValueBindings(SqmUtil.java:401) at org.hibernate.query.sqm.internal.SqmUtil.createJdbcParameterBindings(SqmUtil.java:326) at org.hibernate.query.sqm.internal.ConcreteSqmSelectQueryPlan.buildCacheableSqmInterpretation(ConcreteSqmSelectQueryPlan.java:393) at org.hibernate.query.sqm.internal.ConcreteSqmSelectQueryPlan.withCacheableSqmInterpretation(ConcreteSqmSelectQueryPlan.java:300) at org.hibernate.query.sqm.internal.ConcreteSqmSelectQueryPlan.performList(ConcreteSqmSelectQueryPlan.java:276) at org.hibernate.query.sqm.internal.QuerySqmImpl.doList(QuerySqmImpl.java:571) at org.hibernate.query.spi.AbstractSelectionQuery.list(AbstractSelectionQuery.java:363) at org.hibernate.query.sqm.internal.QuerySqmImpl.list(QuerySqmImpl.java:1073) at org.hibernate.query.Query.getResultList(Query.java:94) While this might seem contrived on its own, it happens with the following spring data code: @Embeddable data class AnEmbeddable(@Column(nullable = false) val foo: String, @Column(nullable = false) val bar: String) interface HasEmbeddable{ val e: AnEmbeddable } @Entity class WithEmbedded(@Id val id: Long, @Embedded override val e: AnEmbeddable): HasEmbeddable @NoRepositoryBean interface HasEmbeddableRepository<T: HasEmbeddable, ID, in AnEmbeddable> : JpaRepository<T, ID>{ fun findByE(e: AnEmbeddable): List<WithEmbedded> } interface WithEmbeddedRepository: HasEmbeddableRepository<WithEmbedded, Long, AnEmbeddable> Please find a hibernate test here: https://github.com/noffke/criteria-embedded-parameter-test ( https://github.com/noffke/criteria-embedded-parameter-test ) Corresponding test case for spring data: https://github.com/noffke/spring-data-jpa-embedded-test/blob/master/src/t...
