Emmanuel Bernard commented on ANN-527:
--------------------------------------

" If someone wants to exchange the implementation of an entity. "
Like I said, I don't see any decent usecase.

> It is only possible to reference a targetEntity by class.
> @ManyToMany(targetEntity = TestImpl.class)
> List<Test> myList;
> This makes it impossible to exchange TestImpl.class implemention by another implemention by the mappings definition.
> It would be helpful to reference a targetEntity by name.
> @ManyToMany(targetEntityName = "Test")
> This would help a lot to implement moduls and frameworks.
> Another way to support this would be to search for a implementation of the collection elements (which are typically Interfaces) in the mapped entities
