Is the Hessian class SerializerFactory thread-safe?

Question

I'd like to use the Hessian (Java) serialization and need to create a SerializerFactory with custom serializers (to handle BigInteger). Can I create one of these and share it among threads?

Answer 1

If you look at the source code, then you can notice that SessionFactory stores created serializers in a HashMap, and HashMap is not a thread-safe object. There is an intresting post about it.

So, the answer to your question is "no".
