[rules-users] repository in 5.2.M2 crashes in 5.2.Final because of decision table serialization

[Michael Anstis]

I am only aware of the changes made around the dtable XML.

Declarative fact types would be an interesting one as that had a few changes
made too to support CEP (addition of annotations).

I am unaware of the difficulties with processes. Somebody else here may be
able to comment.
