Hi ,

I am facing issues while retrieving data for entities having bi-directional manytomany relationship. If I use List for storing entities , i get unable to fetch multiple bags simultaneously error. If i change my code to use Set , i get stackoverflow error.

Details :

Spring 3.0.3
Hibernate-core : 3.5.1-Final
Hibernate-annotations : 3.5.1-Final
hibernate-common-annotations : 3.2.0-Final
hibernate-entitymanager : 3.5.1-Final
Mysql database
Junit 4

User has Many Bank Accounts
Bank Account can have many users

User.java

@ManyToMany(fetch = FetchType.EAGER, mappedBy="user")
private List<BankAccount> bankAccounts = new ArrayList<BankAccount>();

BankAccount.java

ManyToMany(fetch = FetchType.EAGER)
@JoinTable(name = "user_bankaccount", joinColumns = @JoinColumn(name ="bank_account_id"), inverseJoinColumns = @JoinColumn(name = "user_id"))
private List<User> user = new ArrayList<User>();

DB Tables

Users
user_id PK

Bankaccount
bank_account_id PK


user_bankaccount
bank_account_id PK ( references bankaccount.bank_account_id )
user_id PK ( references user.user_id )


issues

1. when i try to get all the users data (getAllUsers) using a junit testcase, i get unable to fetch multiple bags simultaneously error.
2. If I use Set and HashSet instead of List and ArrayList respectively, i get stackoverflow error.

Please help me and let me know if code is wrong or its a known hibernate issue with specific version of libs that i am using.

Thank you.
