Hyperion does not seem to deserialize ObjectDisposedException. Got many problems because it was wrapped in some messages containing the Exception but could reproduce it in the end with this simple lines:

var message = new ObjectDisposedException("oh no");
var serializer = system.Serialization.FindSerializerFor(message);
var binary = serializer.ToBinary(message);
var msg = serializer.FromBinary(binary, null);

Error is:

An exception occurred, System.MissingMethodException: No parameterless constructor defined for this object.

The error feels misleading as most immutable Akka messages do not have a parameterless constructor. Also it does not mention the class where it misses the constructor. I wrapped the Akka.Serialization.HyperionSerializer with my own Akka serializer but I could also track the outer-most parent class. That was in my case Akka.Actor.Status.Failure so it took my a while to go down to ObjectDisposedException.

Versions:

• Akka 1.2.3
• Akka Remote 1.2.3
• Akka.Serialization.Hyperion 1.2.3.43-beta
• Hyperion 0.9.2

A temporary workaround to replace those instances with null would be appreciated.
