Hiberanate 6.4 - JPA persitence unit not found. SAXParser issue with persistence.xml

Question

Please advise or help with this error that I keep getting when running a jUnit in a simple JPA/Hibernate project. The entire setup is trivial because I want to ensure it is bare bones to isolate the issue first.

I am using Windows 11 Home, Java 17 SDK, Hibernate 6.4.0 and Maven 3.9.

Stacktrace is,

    Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.312 s <<< FAILURE! -- in come.lets.learn.AppTest
come.lets.learn.AppTest -- Time elapsed: 0.312 s <<< ERROR!
