Gail Badner commented on HHH-2299:
----------------------------------
Basically, entities are modeled using HashMap objects, rather than an object of an
explicitly defined class. Each entity property is modeled as a Map.Entry using the
property name and value as the key-value pair.
I have verified that the exception does not arise when the test is converted to use
"pojo" entity mode.
A PortalUser "theUser" and a PortalRole "theRole" are created as
HashMap objects. theRole is added to the theUser's set of roles and theUser is added
to theRole's set of users. A Query is used to read the user.
The following leads to the exception:
1) "theUser" is read from the DB into a HashMap. Since a PortalUser has a
non-lazy set of PortalRoles, theUser's roles are read from the DB into an ArrayList in
a PersistentSet "roles", containing only theRole. Since a PortalRole has a lazy
set of PortalUsers. theRole's users are not read.
2) The last step to initialize a PersistentSet involves adding the elements from an
ArrayList into a HashSet. When computing the hash code for theUser's roles, the
hashCode method is ultimately called on theRole's "users" entry which is an
uninitialized PersistentSet. PersistentSet.hashCode() forces initialization of
theRole's users, even though it is supposed to be lazy. theRole's users include
only theUser.
3) The last step to initialize theRole's users, also a PersistentSet, is to add the
user elements from an ArrayList to a HashSet. In the process, the hashCode() method on
theUser's roles PersistentSet, again forcing initialization of the original user's
set of roles. Because, that user's roles are already in the process of being
initialized, the exception is thrown.

Ok, but for what is needs to read a lazy PersistentSet in hashCode() method?!
Why not to use a naitive JDK version of hashCode as in PersistenBag?. In this case
LazyInitializationException is not occure.

Maxim Karavaev commented on HHH-2299:
-------------------------------------
I have the similar proplem... Let's say, we have a two entity A and B with
bidirectional relation:
<class entity-name="A" table="TABLE_A">
<id column="ID" name="id" type="int"/>
<set name="Bs" table="TABLE_AB">
<key column="B_ID"/>
<many-to-many column="A_ID" entity-name="B"/>
</set>
</class>
<class entity-name="B" table="TABLE_B">
<id column="ID" name="id" type="int"/>
<set name="As" table="TABLE_AB"
inverse="true">
<key column="A_ID"/>
<many-to-many column="B_ID" entity-name="A"/>
</set>
</class>
I use hibernate in EJB environment. Method of some session bean:
...
public void addLinkA2B( Integer a_id, Integer b_id )
throws FinderException, CreateException
{
final Session session = getSession();
final Session dSession = session.getSession( EntityMode.MAP );
try
{
final Map a_instance = ( Map )dSession.get( "A", a_id );
if( a_instance == null )
{
throw new FinderException( "Add link failed for due to '" +
a_id + "' not found" );
}
final Map b_instance = ( Map )dSession.get( "B", b_id );
if( b_instance == null )
{
throw new FinderException( "Add link failed for due to '" +
b_id + "' not found" );
}
final Collection links = ( Collection )a_instance.get( "Bs" );
links.add( b_instance );
dSession.flush();
}
catch( HibernateException e1 )
{
throw new CreateException( "Add link failed due to " + e1.toString()
);
}
finally
{
session.close();
}
}
...
and now, testcase:
...
test.createA( 1 );
test.createA( 2 );
test.createB( 1 );
test.addLinkA2B( 1, 1 );
// next line throws a LazyInitializationException
test.addLinkA2B( 2, 1 );
test.createB( 2 );
test.addLinkA2B( 1, 2 );
test.addLinkA2B( 2, 2 );
...
(full source attached)
In the log file, at first invocation of addLinkA2B:
Hibernate: select a0_.ID as ID479_0_ from TABLE_A a0_ where a0_.ID=?
Hibernate: select b0_.ID as ID481_0_ from TABLE_B b0_ where b0_.ID=?
Hibernate: select bs0_.B_ID as B1_1_, bs0_.A_ID as A2_1_, b1_.ID as ID481_0_ from
TABLE_AB bs0_ left outer join TABLE_B b1_ on bs0_.A_ID=b1_.ID where bs0_.B_ID=?
Hibernate: select as0_.A_ID as A2_1_, as0_.B_ID as B1_1_, a1_.ID as ID479_0_ from
TABLE_AB as0_ left outer join TABLE_A a1_ on as0_.B_ID=a1_.ID where as0_.A_ID=?
Hibernate: insert into TABLE_AB (B_ID, A_ID) values (?, ?)
Nice. The next invocation (when set is not empty):
Hibernate: select a0_.ID as ID479_0_ from TABLE_A a0_ where a0_.ID=?
Hibernate: select b0_.ID as ID481_0_ from TABLE_B b0_ where b0_.ID=?
Hibernate: select bs0_.B_ID as B1_1_, bs0_.A_ID as A2_1_, b1_.ID as ID481_0_ from
TABLE_AB bs0_ left outer join TABLE_B b1_ on bs0_.A_ID=b1_.ID where bs0_.B_ID=?
Hibernate: select as0_.A_ID as A2_1_, as0_.B_ID as B1_1_, a1_.ID as ID479_0_ from
TABLE_AB as0_ left outer join TABLE_A a1_ on as0_.B_ID=a1_.ID where as0_.A_ID=?
Hibernate: select bs0_.B_ID as B1_1_, bs0_.A_ID as A2_1_, b1_.ID as ID481_0_ from
TABLE_AB bs0_ left outer join TABLE_B b1_ on bs0_.A_ID=b1_.ID where bs0_.B_ID=?
ERROR [org.hibernate.LazyInitializationException] illegal access to loading collection
Recursion initializing of a LAZY collections! And all this problems only in
PersistentSet.hashCode() method. I just use a "bag" instead of "set"
to avoid this problem, but this solution adds a some new ones.
So again, Why not to use a naitive JDK version of hashCode as in PersistenBag?

------------------------------------
i succeeded working with Set when i removed the bi-directional reference , and used an
unidirectional reference .
this neutralized the recursion of the initialization as was mentioned before .
the bug still exists for bi-directional reference .

Jeffrey Vroom commented on HHH-2299:
------------------------------------
We have also hit this problem when using dynamic models with hibernate. It appears to be
that there are two main problems with the code:
1) hashCode/equals for the dynamic objects hibernate returns is still using the
AbstractMap's implementation which compares every key/value for equality. The
correct behavior in the docs is to use natural keys but there's no way to specify
natural keys (as far as I know). I think using the object's identity would be a
better default (or as Maxim suggests use instance identity). This would avoid the
recursion and the error.
2) It also seems like the code should be marking the list as loaded before it puts it into
the map. That also would avoid this error without changing equals/hashCode.

I ran into similar troubles while using a bidirectional one to many association (to model

Fix would be highly appreciated.

lolo.put("roles",roles);
So I guess it's about resolving roles relationship during obtaing a user object
