IIRC the problem wasn't in JDBC or Cayenne per se. It was "shortcuts"
taken by Hessian serialization (don't recall the exact details). It
is worth trying it again with the new version of hessian that we are
using now.

However when we tried to add that directly to Cayenne an exception

Is there any conceptual reason why this should not work? I'd have
thought that in theory any class could be mapped to a field in
Cayenne, as long as it could be serialised and the JDBC adaptor can
successfully translate the class or its superclass to SQL.
