 Post subject: @ManyToOne + lazy + referencedColumnName doesn't lazy

First; Sorry for the cranky subject but this forum doesn't allow enough chars in subject to write usefull ones...

Anyway; In Hibernate-4.1.2 (an probably other versions) I noticed that using "referencedColumnName" on a @JoinColumn in a @ManyToOne-association makes the lazy-loaded entity fore a load.

Take this mapping:

Code:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "created_by", referencedColumnName = "natural_id")
private Person person = null

When mapping it using Person's PK (and hence skipping the referencedColumnName-attribute from the @JoinColumn-annotation) Hibernate correctly doesn't load the association because it's declared LAZY, but mapping it using an alternate key (here "natural_id") makes Hibernate trigger a load of the lazy-loaded association.

Any way around this?

Thanks.

I have same/similar problem posted:
@manytoone not lazy loaded - always additional select(s)
but no solution by now.
I'd post any advance.

Thanks, Daniel

I reported this issue here: https://hibernate.onjira.com/browse/HHH-7526

Feel free to vote for it.

Let's hope someone will address this soon as it makes working with legacy-databases a pain.
