Yeah, something like that. Also Cayenne's own object access since 3.0
is fully based on pluggable ClassDescriptors, so declaring read/
writeProperty on the object is not needed for Cayenne, and technically
only the generic objects need such user-facing methods.

Actually with Hessian it may be only marginally larger with HashMap
(IIRC
how it does map serialization). With Java serialization it will be
significantly larger, as it likely serializes all the hash bucket
structure.
In any event, like I said in another thread, if we are to reconcile
the
object structures between ROP and regular Cayenne, I'd rather we
move closer
to POJO instead of away from it (with important exception being
support for
generic objects). POJO's take less memory, have no threading issues
and are
generally easier to understand by the users.

Are you sure serialization speed/size for Hessian/java
serialization
will be
better for class with 10 attributes than class with one HashMap
attribute,
*probably* containing those attributes? (and why?)
