Emmanuel Bourg commented on IO-487:
-----------------------------------
Another idea we could consider, if trusting some packages or classes by default
isn't desirable we could provide one or several preconfigured instances of
ValidatingObjectInputStream. For example
{{ValidatingObjectInputStream.DEFAULT}} would provide an implementation
accepting basic types (java.lang.*, Date, URL, etc).
{{ValidatingObjectInputStream.ALL}} would accept everything and would then be
restricted with {{reject()}} calls.
The preconfigured instances can either be provided as static fields
({{ValidatingObjectInputStream}} will have to become immutable similarly to
{{CSVFormat}}) or by static methods.
> ValidatingObjectInputStream contribution - restrict which classes can be
> deserialized
