> Just ran into a bug involving serializing case classes that contain arrays of other case classes: in that situation, we deserialize the nested array as an Array[Product] instead of Array[SpecificCaseClass]. The fix is pretty easy, we just need to use the actual runtime class (i.e., Class[SpecificCaseClass]) as the basis of the PType, instead of Class[Product].
