Hi Luis,
This is related to a "fix" for another bug around OpenJPA and
temporary classloaders required for OpenJPA's dynamic byte code
enhancing. I use fix in quotes because it's one of those situations
where none of the solutions are perfect and each has it's own
drawbacks. For your 3.1.1 install you can set this flag as so which
should allow OpenJPA to see the annotation again:
openejb.tempclassloader.skip=annotations
In the current 3.1.2 code you should be able to run without that flag
set.

Hi all.
I've upgraded to OpenEJB 3.1.1, and having an issue with mappings
using OpenJPA specific annotations, such as @Persistent to persist
an InputStream as blob.
The strange part is that I was already using OpenJPA 1.2.1 with
OpenEJB 3.1.0, and without problems. If I revert to this version,
everything works ok.
Previously I had the same problem when I accidentally left the
openjpa-XXX.jar file in WEB-INF/lib (thus @Persistent was defined in
2 separate classloaders, the global and the web-app specific, which
caused problems). That's not the case now.
The exception root cause:
Caused by: <openjpa-1.2.0-r422266:683325 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Embedded property
"nl.strohalm.cyclos.entities.customization.images.Image.image"
declares a mapping override for "contents", but that is not a
persistent property in the embedded type.

Can anybody help?
