[hibernate-issues] [JIRA] (HHH-15605) Date comparisons with attributeconverters for Zoneddatetime broken since Hibernate 6.1.2

Hannes Rosenögger ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5ec3d02... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNmQ1Yjc1MTJk... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15605?atlOrigin=eyJpIjoiNmQ1Yj... ) HHH-15605 ( https://hibernate.atlassian.net/browse/HHH-15605?atlOrigin=eyJpIjoiNmQ1Yj... ) Date comparisons with attributeconverters for Zoneddatetime broken since Hibernate 6.1.2 ( https://hibernate.atlassian.net/browse/HHH-15605?atlOrigin=eyJpIjoiNmQ1Yj... ) Change By: Hannes Rosenögger ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5ec3d02... ) In one of my applications, we use an attribute converter to store zoneddatetime objects as human-readable strings in the database. This works just fine with hibernate 5.6.11 and even 6.1.1 , but in hibernate 6.1. 4 2 and newer it suddenly breaks when comparing dates. Normal crud operations work as intended. The error message with hibernate 6 is: {noformat}java.lang.IllegalArgumentException: Unsure how to handle given Java type [java.lang.String] as TemporalType#TIMESTAMP{noformat} I’ve created a small sample project to showcase the behavior: [https://github.com/123Haynes/data-jpa-demo/blob/main/src/test/java/com/ex... branch with spring boot 2.7.4 and hibernate 5.6.11, testcase works as intended) [https://github.com/123Haynes/data-jpa-demo/blob/spring-boot-3/src/test/ja...] (branch spring-boot-3 with hibernate 6.1.4, testcase fails with the error mentioned) I tested this with a h2 and a hsql database, same error so I don’t think it’s database specific. I’m not sure if I missed something that I need to change in the release notes, or if this usecase is really broken. Any help with this would be greatly appreciated. 🙂 ( https://hibernate.atlassian.net/browse/HHH-15605#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15605#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
