Description Karen Butzke

In JPA 1.0 only Basic and Transient mappings were support inside of Embeddables.  

In JPA 2.0 the supported mapping types are:
basic
many-to-one
one-to-many
one-to-one
many-to-many
element-collection
embedded
transient

We need to relax the validation error that we give when an attribute mapping type is not supported in a particular type.

There is more to this than just changing a validation error.  One big change is Embeddables supporting references to other Entities, this means supporting association-overrides on embedded mappings.

I will enter another bug for nested Embeddables.

association-overrides now need to support the join-table element

comment # 2 is now bug 281389.

I have  relaxed the validation error to support the new mapping types.  I will include supporting association-overrides on Embedded mappings in this bug and leave it open.

This is completed in the Generic 2.0 model (java and orm) for M2.  Association overrides are supported on embedded mappings and association overrides also support join-tables.  The additional mapping types are now allowed, no validation error for these cases. 

In M3 we will add the support to the EclipseLink 2.0 model.

The eclipselink 2.0 support has been added for M3
