Yes, it just does not work

com.google.gwt.user.client.rpc.SerializationException: Type
'java.math.BigInteger' was not included in the set of types which can be
serialized by this SerializationPolicy or its Class object could not be
loaded. For security purposes, this type will not be serialized.:
instance = 123

Oh, so this is about use with GWT-RPC then, not BigInteger by itself.
Can you show your code that fails?
The information helped me:
Make sure your generics at least implement some interface and you'll be good to go;
the compiler then sees the classes that need to be on the whitelist, as they are referenced
in the RPC method (references via this interface)

(e.g. instead of  HashMap<String,Object>, use HashMap<String,MyInterface>)
