Serialization exception when using rawtypes #539

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Crux explodes an exception if I try to serialize (at server side) a type with 
no raw type defined, like: private java.util.ArrayList myList; ... instead of 
declaring: java.util.ArrayList<MyDTO> myList.

Stack:
