Unsupported class file major version 61, trying to migrate from Java 11 to Java 17

I try to migrate a Java 11 project to Java 17. With Java 11 environment, the project runs without any issues. But in Java 17 I get the following error:

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.791 s <<< FAILURE! - in userservice.controller.UserControllerTest
userservice.controller.UserControllerTest  Time elapsed: 1.791 s  <<< ERROR!
java.lang.RuntimeException: java.lang.ExceptionInInitializerError
Caused by: java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: Failed to start quarkus
Caused by: java.lang.RuntimeException: Failed to initialize Arc
Caused by: java.lang.ExceptionInInitializerError
Caused by: org.hibernate.bytecode.enhance.spi.EnhancementException: Failed to enhance class userservice.persistence.entities.UserEntity
Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 61

My UserEntity class looks like this:

package userservice.persistence.entities;

import javax.persistence.*;
import java.util.Objects;

@Entity(name="user")
@Table(name="user")
@NamedQuery(name = "User.findAll", query = "SELECT u FROM user u ORDER BY u.email")
@NamedQuery(name = "User.findByEmail", query = "SELECT u FROM user u WHERE u.email = :email")
public class UserEntity {

    public static final String QUERY_FIND_ALL = "User.findAll";
    public static final String QUERY_FIND_BY_EMAIL = "User.findByEmail";

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(unique = true)
    private String email;

    public UserEntity() {}

    // basic setter, getter for email and id...
    // and basic equals, toString and hashCode methods...

}

What am I missing..would be glad if someone could help me.
