If I change one of the failing tests to move the @Id to the fields, I get a different failure: diff --git a/hibernate-core/src/test/java/org/hibernate/orm/test/bytecode/enhancement/merge/MergeDetachedNonCascadedCollectionInEmbeddableTest.java b/hibernate-core/src/test/java/org/hibernate/orm/test/bytecode/enhancement/merge/MergeDetachedNonCascaded CollectionInEmbeddableTest.java index e7cea27725..8900c29a4f 100644 --- a/hibernate-core/src/test/java/org/hibernate/orm/test/bytecode/enhancement/merge/MergeDetachedNonCascadedCollectionInEmbeddableTest.java +++ b/hibernate-core/src/test/java/org/hibernate/orm/test/bytecode/enhancement/merge/MergeDetachedNonCascadedCollectionInEmbeddableTest.java @@ -37,7 +37,7 @@import org.junit.jupiter.api.Test;                } ) @SessionFactory -@BytecodeEnhanced +@BytecodeEnhanced(testEnhancedClasses = {Heading.class, Grouping.class, Thing.class}) public class MergeDetachedNonCascadedCollectionInEmbeddableTest {        @Test @@ -64,12 +64,12 @@public class MergeDetachedNonCascadedCollectionInEmbeddableTest {        @Entity(name = "Heading")        public static class Heading { +@Id +@GeneratedValue                private long id;                private String name;                private Grouping grouping; -               @Id -               @GeneratedValue                public long getId() {                        return id;                } @@ -112,10 +112,10 @@public class MergeDetachedNonCascadedCollectionInEmbeddableTest {        @Entity(name = "Thing")        public static class Thing { -               private long id; -                @Id                @GeneratedValue +private long id; +                public long getId() {                        return id;                } Error: <testcase name="initializationError"classname="org.hibernate.orm.test.bytecode.enhancement.merge.MergeDetachedNonCascadedCollectionInEmbeddableTest"time="0.001"> <failure message="org.hibernate.MappingException: Basic collection has element type 'org.hibernate.orm.test.bytecode.enhancement.merge.MergeDetachedNonCascadedCollectionInEmbeddableTest$Thing' which is nota known basic type (attribute is notannota ted '@ElementCollection', '@OneToMany', or &#39;(a)ManyToMany&#39;)&quot;type=&quot;org.hibernate.MappingException&quot;&gt;org.hibernate.MappingException: Basic collection has element type 'org.hibernate.orm.test.bytecode.enhancement.merge.MergeDetachedNonCascadedCollectionInEmb eddableTest$Thing' which is nota known basic type (attribute is notannotated '@ElementCollection', '@OneToMany', or '@ManyToMany')        at app//org.hibernate.type.descriptor.java.spi.BasicCollectionJavaType.getRecommendedJdbcType(BasicCollectionJavaType.java:72)        at app//org.hibernate.boot.model.process.internal.InferredBasicValueResolver.from(InferredBasicValueResolver.java:195) So further test changes may be needed but I have to ask if I should be modifying the failing tests?  Or should we introduce a way for tests/applications to configure a service or configuration property to determine whether the https://github.com/hibernate/hibernate-orm/pull/9136 change applies to their application (via config property) or the platform that ORM is part of (via new service)? I also single stepped through the https://github.com/hibernate/hibernate-orm/pull/9136 changes while running the MergeDetachedNonCascadedCollectionInEmbeddableTest.testMergeDetached test to verify that nothing unexpected is happening in the added code while running this test.
