When having the following entities:
{code:java}
@Entity(name = "Post")
@Table(name = "post")
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
public static class Post {
@Id
private Long id;
private String title;
@Version
private int version;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "post", orphanRemoval = true)
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
private List<PostComment> comments = new ArrayList<>();
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public List<PostComment> getComments() {
return comments;
}
public void addComment(PostComment comment) {
comments.add(comment);
comment.setPost(this);
}
}
@Entity(name = "PostComment")
@Table(name = "post_comment")
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
public static class PostComment {
@Id
private Long id;
@ManyToOne(fetch = FetchType.LAZY)
private Post post;
private String review;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Post getPost() {
return post;
}
public void setPost(Post post) {
this.post = post;
}
public String getReview() {
return review;
}
public void setReview(String review) {
this.review = review;
}
}
{code}
and bootstrapping Hibernate 5.3.2 with `properties.put("hibernate.cache.region.factory_class", "ehcache");` we get the following exception:
{noformat}

This used to work just fine with Hibernate 5.2. |
