Hibernate Search tries to guess fieldbridges for unindexed entities

Question

I'm trying to use Hibernate Search (4.4.0) in a project with a large object model (>200 entities). Of these, I want to index only a few entities; currently just a single one. I added the @Indexed, @DocumentId and @Field annotations as appropriate to the entity.

However, when I deploy my artifact and start the application server, I'm getting an error message "HSEARCH000135: Unable to guess FieldBridge for [field] in [type]" for the primary key of an entity that is in the same persistence unit, but completely unrelated to the indexed entity.

I don't want to specify custom fieldbridges for entity primary keys that I don't intend to index, as this would take a long time to implement on the complete object model.

My questions are: why is this happening? Is there any way around this?

For reference, the complete stacktrace is given below:

So this was a bug (https://hibernate.atlassian.net/browse/HSEARCH-1447) that has been fixed for a long time now. The solution is to use at least version 4.4.3.Final of Hibernate Search.
