Rick Curtis commented on OPENJPA-1612:
--------------------------------------
Pinaki -
I'll start off by saying that I'm not dead set on this commit by any means. The
intent of this commit was to improve the usability of OpenJPA, but it sounds
like I may have sacrificed some functionality that we used to have.
The problem I was trying to fix is as follows:
* Joe user has two Entities {A,B} and A has a @OneToOne to B.
* Joe messes up when he specifies <class>(s) in his p.xml file and omits B.
* Prior to this commit, OpenJPA took the liberty to serialize B to save it to
the DB. Perhaps there are certain use cases where this would be okay, for the
sake of the test it wasn't.
Since javax.persistence.xTox annotations are defined by the spec, I don't think
we have the liberty to define them in any way we like. My understanding is that
these annotations are for Entity to Entity relationships. The code I added
checks for this and fails fast.

> Reporter: Rick Curtis
> Assignee: Rick Curtis
> Priority: Minor
> Fix For: 2.1.0

> As discussed on the dev mailing list [1]...
> I found that the following mapping:
> @Entity
> public class AnnoTest1 {
> @ManyToOne
> Object o;
> ...
> }
> This results in a warning message [2], but it is allowed. This JIRA will be
> used to detect this condition and fail fast.

> [2] 297 TestConv WARN [main] openjpa.MetaData - OpenJPA cannot map field
> "test.AnnoTest1.o" efficiently. It is of an unsupported type. The field
> value will be serialized to a BLOB by default.
