Sands Fish commented on DS-296:
-------------------------------
We are seeing these exceptions very regularly in our 1.6.0 instance.
Does anybody know if this is as simple as patching that file to be
serializable? Or is there any danger in that?

> Key: DS-296
> URL: http://jira.dspace.org/jira/browse/DS-296
> Project: DSpace 1.x
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 1.5.2, 1.6.0
> Reporter: Flávio Botelho
> Priority: Minor
>
> For some reason, the code wants to serialize
> org.dspace.app.xmlui.cocoon.DSpaceFeedGenerator, should it?
> If so than it needs to implement serializable.
> Else somewhere there is a pointer to such an object that shouldn't be.
