US Patent 10120777 Remediating serialization incompatibilities

Techniques for remediating serialization incompatibilities are disclosed. A runtime environment of a module system identifies a first serializable runtime object comprising a reference to a second serializable runtime object. The first serializable runtime object is an instantiation of a first element in a first package of the module system. The first package is open to one or more reflective operations. Based on determining that (a) the second serializable runtime object is an instantiation of a second element in a second package of the module system and (b) the second element is not open to the one or more reflective operations, a remedial operation, associated with the first serializable runtime object, is executed.
