Message Title

After upgrading to Spring Boot 3 and Hibernate 6, I have a use case not working about an enum :

    @Column(name = "way", length = 1)
    @Enumerated(EnumType.STRING)
    private Way way;

// Forward(Aller in french), Backward(Retour in french)
    public enum Way {A,R}

CREATE TABLE working
(
    id  VARCHAR PRIMARY KEY NOT NULL,
    way VARCHAR(1)
);

Expecting code not to raise a throwable but caught

I hope it’s enough, I tried to make a test case directly in hibernate-core and submit a PR, but I lacked enough knownleged to make it work 🙂
