[hibernate-issues] [JIRA] (HHH-14006) Extended Bytecode enhancement fails for inherited public fields

Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiM2FkYmFhNmFh... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-14006?atlOrigin=eyJpIjoiM2FkYm... ) HHH-14006 ( https://hibernate.atlassian.net/browse/HHH-14006?atlOrigin=eyJpIjoiM2FkYm... ) Extended Bytecode enhancement fails for inherited public fields ( https://hibernate.atlassian.net/browse/HHH-14006?atlOrigin=eyJpIjoiM2FkYm... ) Issue Type: Bug Affects Versions: 5.4.15 Assignee: Unassigned Components: bytecode-enhancement Created: 07/May/2020 06:19 AM Fix Versions: 5.4-backlog Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) This might be a duplicate of HHH-12601 ( https://hibernate.atlassian.net/browse/HHH-12601 ) Open , but the code mentioned in that ticket is completely different from the one I encountered while analyzing the problem, so I'm not sure. When you define a public field in a mapped superclass or in an entity superclass, inherited by an entity class: @Entity(name = "entitySuper" ) @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public static class MyEntitySuperClass { @Id @GenericField public Integer id; } @Entity @Indexed public static class MyEntity extends MyEntitySuperClass { @Basic public String name; } And access the id defined in the superclass on an instance of the child class: MyEntity entity1 = new MyEntity(); entity1.id = 1; // Id is not defined in MyEntity, but in its superclass Then enhancement of the code above will fail with this error: Caused by: org.hibernate.bytecode.enhance.spi.EnhancementException: Failed to enhance class org.hibernate.search.integrationtest.mapper.orm.model.BytecodeEnhancementIT at org.hibernate.bytecode.enhance.internal.bytebuddy.EnhancerImpl.enhance(EnhancerImpl.java:138) at org.hibernate.testing.bytecode.enhancement.BytecodeEnhancerRunner$EnhancingClassLoader.loadClass(BytecodeEnhancerRunner.java:219) ... 18 more Caused by: org.hibernate.bytecode.enhance.spi.EnhancementException: Unable to perform extended enhancement - No unique field [id] defined by [org.hibernate.search.integrationtest.mapper.orm.model.BytecodeEnhancementIT$IndexedEntity] at org.hibernate.bytecode.enhance.internal.bytebuddy.FieldAccessEnhancer.findField(FieldAccessEnhancer.java:131) at org.hibernate.bytecode.enhance.internal.bytebuddy.FieldAccessEnhancer.access$000(FieldAccessEnhancer.java:33) at org.hibernate.bytecode.enhance.internal.bytebuddy.FieldAccessEnhancer$1.visitFieldInsn(FieldAccessEnhancer.java:66) at net.bytebuddy.jar.asm.ClassReader.readCode(ClassReader.java:2415) at net.bytebuddy.jar.asm.ClassReader.readMethod(ClassReader.java:1488) at net.bytebuddy.jar.asm.ClassReader.accept(ClassReader.java:718) at net.bytebuddy.jar.asm.ClassReader.accept(ClassReader.java:401) at net.bytebuddy.dynamic.scaffold.TypeWriter$Default$ForInlining.create(TypeWriter.java:3827) at net.bytebuddy.dynamic.scaffold.TypeWriter$Default.make(TypeWriter.java:2166) at net.bytebuddy.dynamic.scaffold.inline.RedefinitionDynamicTypeBuilder.make(RedefinitionDynamicTypeBuilder.java:224) at net.bytebuddy.dynamic.DynamicType$Builder$AbstractBase.make(DynamicType.java:3588) at org.hibernate.bytecode.internal.bytebuddy.ByteBuddyState.make(ByteBuddyState.java:197) at org.hibernate.bytecode.internal.bytebuddy.ByteBuddyState.rewrite(ByteBuddyState.java:146) at org.hibernate.bytecode.enhance.internal.bytebuddy.EnhancerImpl.enhance(EnhancerImpl.java:132) ... 19 more ( https://hibernate.atlassian.net/browse/HHH-14006#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-14006#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
