That's always a good indication that plugin.xml extension registrations 
that are needed have been overlooked.

Can you tell if a different resource factory is being used to create the 
resource in each case?

Normally it should never try to create an instance of an abstract type 
because the serialization will contain either an xsi:type or a QName to 
represent the concrete type that should be used.   I suspect that the 
different options being used in each case are causing the problem....
