Hibernate.initialize() ignores lazy?

Hibernate version: 3.2

Basically I have a class containing a collection of a class that contains another collection. All mappings for collections are set to be lazy.

Stripped down mapping:

Code:

<class name="TheClass">
      
   <set name="collection1" lazy="true">
      <one-to-many class="OtherClass"/>
   </set>
</class>

<class name="OtherClass">

   <list name="collection2" lazy="true">
      <many-to-many class="YetAnotherClass"/>
   </list>
</class>

First retrieve theClass:

Code:

TheClass theClass = theClassDAO.getTheClass(id);

Since I'm using lazy, collection1 hasn't been loaded. Fine, now I want to load collection1:

Code:

Hibernate.initialize(theClass.getCollection1);

Hibernate will now also load collection2 even though it's tagged as lazy. Is this the default behaviour for Hibernate.initialize()? The entire tree will be loaded?

I had expected only collection1 to be loaded. Much obliged for any comments.

I think something might be off in how you're testing this as I wrote a test myself yesterday and it worked how I had expected it to. i.e. only the first level was initialized and when I tried to access the 2nd level after the session was closed it blew the lazy initialization exception.
