Hi,

While fixing HSEARCH-1201, we introduced a bug in commit: https://github.com/hibernate/hibernate-search/commit/2f7844857bfafb951564ae136e646f6cf801add2

This bug causes the mass indexer to not index relations if they are proxyfied. In our case, we didn't have any error but after a mass indexing, our indexes didn't contain the information from @IndexedEmbedded fields, as soon as we put a LAZY on them.

Pull request to follow with the (trivial) fix: we need to return the initialized object if it's not null.

I'm working on a self contained test case, too.

Sorry for not noticing this issue while I reviewed the patch.
