Why does parseFromArray is not failing when passed with valid different  ProtoBuff message ?

Just to make sure I understand, are you saying you are taking a serialized message of some type A and attempting to parse it as a different type B and you are wondering why it is succeeding despite the mismatch? If so, the answer is that protocol buffers are designed to allow schemas to evolve over time and so it is typical and expected to come across fields that were not present in the schema. The message is probably being interpreted as a B message with a few unknown fields.
