Hello,

Seems that https://hibernate.org/xsd/hibernate-mapping/hibernate-mapping-4.0.xsd has changed on 2022-02-22 and is throwing this message on my application:

Caused by: org.hibernate.InvalidMappingException: Unable to read XML

I had to change temporarily my code and validate against the hibernate-mapping-4.0.xsd i have on my classpath.
Any clue on how to fix that?
Thanks

Try using HTTPS everywhere in your mappings. Seems the XML parser can’t handle redirects.

That solved the issue, thanks!
