Entity has had stable serialization for a very long time. Sometime in recent history it broke:

java.io.InvalidClassException: com.google.protobuf.ByteString; local class incompatible: stream classdesc serialVersionUID = -5687838473930111344, local class serialVersionUID = 2497003577682127865

I notice that ByteString doesn't specify a serialversionuid.

Objectify serializes Entity into memcache, so breaking serialization causes headaches.

Closing as ByteString serialization was fixed
