I know it is an old question, and as you will see the situation was different at that time, but hopefully it can help others researching this issue as I did.

Note: Your edit made it sound like switching to XML by itself was the magic. Yet, looking closer at the code, you had default-lazy-init="true". I wonder if that was the true reason.
