Problem saving object with empty collection
Hello,
I have an object that inherits from a base class that contains a number of collections - 3 sets and 1 list. The collections are initialized to empty collection objects on construction as follows:
@Entity
@Audited
public abstract class Person{
@ManyToMany
@JoinTable(
name = "PeoplesClothes",
joinColumns = {@JoinColumn(name = "personID")},
inverseJoinColumns = {@JoinColumn(name = "clothesID")})
private Set<Clothes> clothes= new HashSet<Clothes>();
@ManyToMany
@JoinTable(
name = "PeoplesThings",
joinColumns = {@JoinColumn(name = "personID")},
inverseJoinColumns = {@JoinColumn(name = "thingID")})
private Set<Thing> costSheet = new HashSet<Thing>();
@ManyToMany
@JoinTable(
name = "PeoplesCars",
joinColumns = {@JoinColumn(name = "personID")},
inverseJoinColumns = {@JoinColumn(name = "carID")})
private Set<Car> route = new HashSet<Car>();
@OneToMany
@OrderBy("priority")
@JoinTable(
name = "PeoplesFriends",
joinColumns = {@JoinColumn(name = "personID")},
inverseJoinColumns = {@JoinColumn(name = "friendID)}
)
@org.hibernate.annotations.IndexColumn(name = "friend_PRIORITY")
private List<Friend> friends= new ArrayList<Friend>();When I try to construct the object and leave the collections empty I get the following error (I think when its processing the list collection - but i am not 100% sure):
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

What is causing this? I have similar code in other classes and it works fine - I don't see what the difference is between the cases where it works and where it doesn't.
Thanks,
