With version 6.0, Hibernate ORM has moved to expect Java 11 as its baseline version. It has also moved from Java Persistence as defined by the Java EE specs to Jakarta Persistence as defined by the Jakarta EE spec. We shall be using the jakarta.persistence. packages instead of javax.persistence. packages, starting from Hibernate version 6.0.
Note that Jakarta provides a transformer tool that can help in transforming a project from Java Persistence to Jakarta Persistence.
