The error is because permisions is defaulting use a field called
"PERMISSIONS" in the database.
You will need to specify the @CollectionTable and @ElementCollection
if you need it to go to a table like your ManyToMany would have.

Hi,
I just change the Permission class from an entity to enum for
simplicity, but it causes errors (the partial stack trace is at
the end).
Is it supported?
@Entity
public class Role {
public static final String NORMAL_ROLE = "normal";
public static final String ADMIN_ROLE = "admin";
public static final String QUERY_SELECT_ALL = "select r from
Role r";
@Id
private String id;
private String name;
//@ManyToMany(cascade = {CascadeType.ALL})
List<Permission> permissions;
...
}
