> The issue reported a ClassCastException "cannot assign instance of > java.util.CollSer to field of type java.util.Map" > while deserializing an object referring to an immutable Map that contained a > reference to a class that was not available. > Immutable Collections such as Map utilize a serialization proxy in their > serialized form. > During deserialization the serialization proxy (a private implementation > class) was attempted to be set in a field resulting in the > ClassCastException. The ClassCastException and bug hid the ClassCastException > that should have been thrown. > > When reading record fields or fields of a class, the results of > deserialization of individual fields are recorded as dependencies of the > object being constructed. > The apparent bug is that the summary of those dependencies is not checked > between reading the fields and invoking the constructor to create the record > or assigning the fields to an object being constructed.
