[JIRA] (HHH-15730) Hibernate throws NullPointerException if loading an Entity that contains a null Embedded field and enableDirtyTracking = true

by Johan Steenkamp (JIRA)

Johan Steenkamp ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=6374fb5... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMzBkNzI3Nzcw... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15730?atlOrigin=eyJpIjoiMzBkNz... ) HHH-15730 ( https://hibernate.atlassian.net/browse/HHH-15730?atlOrigin=eyJpIjoiMzBkNz... ) Hibernate throws NullPointerException if loading an Entity that contains a null Embedded field and enableDirtyTracking = true ( https://hibernate.atlassian.net/browse/HHH-15730?atlOrigin=eyJpIjoiMzBkNz... ) Issue Type: Bug Affects Versions: 6.1.5 Assignee: Unassigned Components: bytecode-enhancement Created: 16/Nov/2022 08:22 AM Environment: Hibernate 6.1.5 JDK 19 Both Windows and Linux SQL Server Priority: Critical Reporter: Johan Steenkamp ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=6374fb5... ) I have a Customer entity that is outlined like this: @Entity public class Customer { ... @Embedded() private Address postalAddress; ... The Address Embeddable looks like this: @Embeddable public class Address implements Serializable { @Basic @Size(max = 50) private String address1; @Basic @Size(max = 50) private String address2; @Basic @Size(max = 50) private String address3; @Basic @Size(max = 50) private String city; @Basic @Size(max = 10) private String postalCode; public Address() { super (); } public Address( final String address1, final String address2, final String address3, final String city, final String postalCode) { this (); setAddress1(address1); setAddress2(address2); setAddress3(address3); setCity(city); setPostalCode(postalCode); } // Getters and setters ... } Now, if I Hibernate loads a Customer entity from the Database where all the address fields are null, it will set the postalAddress address reference in the resulting Customer Object also to null, which I think is correct. In general this null postalAddress reference doesn't cause any issue. However, things start going wrong if I set enableDirtyTracking to true in gradle like this: hibernate { enhancement { enableLazyInitialization = false enableDirtyTracking = true enableAssociationManagement = false enableExtendedEnhancement = false } } With such a setup, as soon as Hibernate tries load a customer that have a resulting null postalAddress reference, I get the following exception: Caused by: java.lang.NullPointerException: Cannot invoke "org.hibernate.engine.spi.CompositeTracker.$$_hibernate_setOwner( String , org.hibernate.engine.spi.CompositeOwner)"

//org.hibernate.proxy.ProxyConfiguration$InterceptorDispatcher.intercept(ProxyConfiguration.java:95) I had a look at the source code of EnhancedSetterImpl.java, where the exception occurs, which I have outlined below. If I have enabled enableDirtyTracking , then it does go into the first if statement shown. In such a case *value* will be null for postalAddress and will cause the NullpointerException. I belief this should be a bug in how enableDirtyTracking works, since it does works fine if I don't enable this. I have tried the same with 6.1.6 by getting the source from Github and compiling it, but I get the same error. @Override public void set( Object target, Object value) { super.set( target, value ); // This sets the component relation for dirty tracking purposes if ( ( enhancementState & COMPOSITE_OWNER ) != 0 && ( ( enhancementState & COMPOSITE_TRACKER_MASK ) != 0 || value instanceof CompositeTracker ) ) { ( (CompositeTracker) value ).$$_hibernate_setOwner( propertyName, (CompositeOwner) target ); } // This marks the attribute as initialized, so it doesn't get lazily loaded afterwards if ( ( enhancementState & PERSISTENT_ATTRIBUTE_INTERCEPTABLE_MASK ) != 0 ) { final PersistentAttributeInterceptable asPersistentAttributeInterceptable = ManagedTypeHelper.asPersistentAttributeInterceptable( target ); PersistentAttributeInterceptor interceptor = asPersistentAttributeInterceptable.$$_hibernate_getInterceptor(); if ( interceptor instanceof BytecodeLazyAttributeInterceptor ) { ( (BytecodeLazyAttributeInterceptor) interceptor ).attributeInitialized( propertyName ); } } } ( https://hibernate.atlassian.net/browse/HHH-15730#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15730#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
