It seems a few problems were introduced with HSEARCH-3082 Resolved , where we create an exception but forget to throw it.

Two things to do:

1. Throw the exception, obviously
2. Add a test for each such problem, because an untested feature is a non-existent feature.

I noticed the problem in org.hibernate.search.mapper.pojo.model.impl.AbstractPojoModelCompositeElement#createAccessor(java.lang.Class<T>), but there may be others.
