This would be quite difficult to implement.

Internally, a one-to-one property-ref looks nothing like a collection.

Subject: [Hibernate] Second level cache and mappedBy side of a FK
one-to-one

Owner side
<many-to-one name="person" class="Person" column="PERSON_ID"
unique="true"/>

mappedBy side
<one-to-one name"employee" class="Employee" property-ref="person"/>

In this case, the owner side is resolved in cache, and not the mappedBy
side (if I load person, employee will be resolved in the 2nd cache, if
employee is loaded, person cannot be resolved in the 2nd level cache)
But the mapped by side is actually some kind of 1 element collection (in
a true bidir many to one we can cache both sides. Would it make sense to
allow caching of the mappedBy side with a same mechanism than the one
used in collections?
