Steve Ebersole ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiOGRkMTlkMGRm... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16572?atlOrigin=eyJpIjoiOGRkMT... ) HHH-16572 ( https://hibernate.atlassian.net/browse/HHH-16572?atlOrigin=eyJpIjoiOGRkMT... ) Bad enhancement for PROPERTY attributes with mismatched field and method names ( https://hibernate.atlassian.net/browse/HHH-16572?atlOrigin=eyJpIjoiOGRkMT... ) Change By: Steve Ebersole ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Consider the model : {code:java}@Entity public static class Spouse { ... private String last; @Id Integer getId() {...}; String getLastName() {...}; void setLastName(String name) {...}; }{code} Here, we have PROPERTY access (getter and setter) because of the placement of {{(a)Id}}. which in turn means that we have a persistent attribute named {{lastName}}based on the getter method name. This confuses the enhancer which always works from the field name.  Here, it thinks the persistent attribute is named {{last}}. ---- Jakarta EE 10 TCK test jpa/core/query/flushmode ( #flushModeTest5 ) [https://github.com/jakartaee/platform-tck/blob/master/src/com/sun/ts/test...] fails. The tests that fail with vehicle names: * flushModeTest5_from_appmanagedNoTx * flushModeTest5_from_pmservlet * flushModeTest5_from_puservlet * flushModeTest5_from_stateless3 The same tests pass with bytecode enhancement disabled. The test output contains: [javatest.batch] ^[[0m^[[0m12:24:15,206 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: Wrong collection size returned (expected 1, got 0) [javatest.batch] ^[[0m^[[0m12:24:15,207 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: Wrong size returned, expected PKs of (11), got PKs of () [javatest.batch] ^[[0m^[[0m12:24:15,207 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: Did not get expected results.  Expected  1 reference, got: 0 [javatest.batch] ^[[0m^[[0m12:24:15,207 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: flushModeTest5 failed [javatest.batch] ^[[0m^[[0m12:24:15,207 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: Test case throws exception: flushModeTest5 failed [javatest.batch] ^[[0m^[[0m12:24:15,207 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: Exception at: [javatest.batch] ^[[0m^[[0m12:24:15,208 INFO  [stdout] (Thread-197) 05-02-2023 12:24:15:  SVR-ERROR: com.sun.ts.lib.harness.EETest$Fault: flushModeTest5 failed [javatest.batch] ^[[0m^[[0m12:24:15,209 INFO  [stdout] (Thread-197)     at deployment.jpa_core_query_flushmode_vehicles.ear.jpa_core_query_flushmode_appmanagedNoTx_vehicle_ejb.jar// ( https://hibernate.atlassian.net/browse/HHH-16572#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16572#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
