[QUESTION] How do Java-based projects handle Hibernate?

Question for the group, since I have seen things that seem contradictory. How do projects handle Hibernate since it's LGPL and as such, a Category X dependency?

It seems like simply using the library is fine. However, then you see things about "linking" to the library, does simply using the classes and the imports mean it's included in the source?

Is that allowed if we're using JPA and OpenJPA for the classes and Hibernate for the implementation?

Along the same lines, what about test libraries?

Hi Jason,

AFAIK it is ok to use it in tests while you don't reference it explicitly
in your code (which means delivering it or implementing its SPI/classes and
you don't let it be transitive in any assembly somehow) so would mean ok to
use in test while you stay under JPA API.
So it would be more JPA for the code, OpenJPA/Hibernate in tests and
OpenJPA for the runtime until you download it at runtime (like Karaf
features can do for ex).
