Code between sessionFactory.openSession() and session.close():

Criteria criteria = session.createCriteria( TimeSheet.class );

criteria.add( Expression.eq( "weekEndDate", weekendDate) );
return (TimeSheet) criteria.uniqueResult();

I see "org.apache.commons.lang.builder.ToStringBuilder" is broken, fix or drop it.

Looks like my original post was truncated. Probably because of the lengthy strack trace. ToStringBuilder is not the problem. It happens even without ToStringBuilder. I've stepped through it in the debugger and here is what is happening.

When I run the query by criteria above...

** SessionImpl.initializeEntity(Object) (line 2226) has a debug that calls toString on the id of the entity being loaded

** In my case the entire object is the id so it calls toString on my persistent object. In my persistent object the entries collection has not been initialized so SessionImpl.initializeCollection is called to initialize the collection.

** In SessionImpl.initializeCollection(PersistentCollection collection, boolean writing) it also calls toString (line 3260) on the id which happens to be my persistent object (with the uninitialized collection). Since the collection is uninitialized it calls SessionImpl.initializeCollection again and now we're in a recursive loop that results in a stack overflow.

So now...

Why is my collection being lazy initialized? I did not specify lazy="true". Doesn't it default to false?

Shouldn't the trace statement in the initializeCollection method be removed to prevent this type of recursive problem?

Do not use the ReflectionToStringBuilder for your toString method. The bi-directional relationship between TimeSheet and TimeSheetEntry causes the toString() method in each class to be called recursively ad infinitum. Instead, use the append() functionality in ToStringBuilder. You probably want to append the Set of TimeSheetEntrys in the TimeSheet class but not the reference to the TimeSheet object in your TimeSheetEntry class.

Hope this helps,

James

We're not using ReflectionToStringBuilder. It has nothing to do with ToStringBuilder. I've rewritten the toString method without ToStringBuilder and still have the problem.

The problem is that hibernate is trying to toString an object that has an uninitialized collection. During that toString the collection must be initialized. During the collection initialization it also toString's the object which requires the collection to be initialized. This results in a recursive loop.

To put it another way... The toString cannot compete until the collection is initialized and the collection cannot be initialized because the first thing that initializeCollection does is toString the object.

Could you post the code for TimeSheet and TimeSheetEntry so I have a complete picture of what you are doing?

deanen · **Joined:** Mon Sep 06, 2004 4:11 pm **Posts:** 6

Hopefully they won't get truncated. I've reverted back to using ToStringBuilder now that I've eliminated it as the problem.

I know the design is not ideal and we're using composite keys but we're kind of stuck with a legacy database that we cannot change without significant impacts to existing applications.

so if you just disable debug logging or change your tostring to not dump non-initialized collections you would not have this problem - correct ?

i've looked at the code now.

The only way we could remove this is to not print the id's in the debug output - but then it gets VERY hard to trace what happens....and I would say that in almost any case (except yours) it should be safe to call toString on a key.

I would suggest to you not to access collections in your toString when you use the complete object as the key (or simply disable debug/trace for that specific hibernate log category that makes the recursive loop happen)
