Summary 0004165: ArrayStoreException on deserializing a class with an unknown field
Description If a Hessian 2 stream contains an object definition with more fields than the class known locally, an ArrayStoreException is triggered:

at com.caucho.hessian.client.HessianProxy.invoke(

This is annoying because if a class is updated on the server with an optional field, it crashes the clients that haven't been updated yet a rely on a older version of the class. It doesn't happen with a Hessian 1 stream.

This happens because NullFieldDeserializer in JavaDeserializer doesn't extend FieldDeserializer, so it's not possible to assign its instance to the array of FieldDeserializers created in the JavaDeserializer#createFields(int) method.
