Comment 1 Remy Suen CLA 2011-06-21 08:21:08 EDT 
Please open EclipseLink bugs with EclipseLink.
Comment 2 Tom Ware CLA 2011-06-23 10:34:12 EDT 
From an email conversation about this bug:

The fault (on our end) seems to lie on reloading a MappedSuperclass (from XML)
to an Embeddable class to create our internal metamodel.

If they annotated the mapped superclass (rather than map it in XML), it may get
them by the problem. Alternatively, it would seem that the embeddable class is
only annotated and if it were mapped in XML it could alleviate the problem
(oddly enough).

So may it may be as simple as adding in XML

<embeddable class="blah"/>

For the embeddable classes that inherit from a mapped superclass.

Proposed changes
Comment 5 Guy Pelletier CLA 2011-07-06 09:39:59 EDT 
Changes have been submitted to both the 2.3.1 and trunk streams.

Verified by: Tom Ware

Tests: Metadata processing error. New test model created, with fix in place no NPE occurs.
Comment 6 Guy Pelletier CLA 2011-09-28 10:11:49 EDT 
*** Bug 358795 has been marked as a duplicate of this bug. ***
Comment 7 michael.munn CLA 2011-11-02 23:18:30 EDT 
Is this included in 2.3.1-M8 ??
Comment 8 Tom Ware CLA 2011-11-03 08:20:46 EDT 
This fix should appear in 2.3.1 M8. (It was fixed quite early in our 2.3.1 development and likely appears as early as M2)
