    Resolution: Won't Fix

Marking won't fix as my IO-487 contribution has been accepted in Apache Commons, we can then use that.

> To avoid a recently reported Java deserialization vulnerability [1], we should restrict which classes are accepted when deserializing binaries.
> I have created a prototype SafeObjectInputStream at [2], which refuses to operate on classes that are outside a whitelist.
> We probably also need a wrapper for ObjectInputStreams provided by the environment, that looks a bit harder to create, for now we can already discuss this prototype to see if we want to pursue the idea.
