I've been working with Hibernate 3.3.2 and Hibernate Search 3.1 for the past few months. We finally got to a point in our project where we are sucking in mass amounts of data into our application from a large business application via JMS.

The error started when I added an @IndexEmbedded annotation to the collection, and I discovered I was missing the @ContainedIn annotation in the collection entity. That didn't fix it. After weeks of doing little tweaks, breaking, fixing, breaking, fixing, I finally discovered the problem. I was using an older manual for Hibernate Search (3.0 specifically) and I had the following configuration parameter pushed into my SessionFactory:

Hibernate Search on The Dangling Pointer
