The problem is that Mutation.equals() calls a private serialize() method
that modifies the data about to be checked. I have successfully worked
around this in the past by wrapping the Mutation in a new Mutation, which
calls serialize under the hood:

 assertEquals(expectedMutation, new Mutation(actualMutation));

This applies to 1.4.x, I don't know if Mutation.equals() has changed since
then.
