Serialize data using java binary serialization system

[mkotsbak]

This is probably the fastest way to get the state saved to be able to use it (but the saved data is brittle, so should be used only for testing).

Does that mean we can only support Serializable objects? Isn't that a huge weakness?

[mkotsbak]

Uhm. More objects are serializable than gson-serializable.

How can you possibly support an object that is not serializable, at least as captured return values (other objects probably are just referred using Method/Class/Type so the objects themself need not to be serializable).

We could maybe support mocking the return values too and respond to the methods called there. This is getting complicated!
