Problem with ProtobufDatumReader

["Gorman,Will" <WG...@CERNER.COM>]

I'm having some difficulty using avro-protobuf  and I'm not sure what I'm doing wrong.  I keep getting a ClassCastException that a Builder cannot be cast to a Message whenever I try to deserialize an object with the ProtobufDatumReader after it was serialized with the ProtobufDatumWriter.  I've looked through the code a bit in ProtobufData and GenericDatumReader but I'm not sure how it's supposed to work because it appears to just be creating a new builder and then passing it to a method that attempts to cast it to a message.  I've got a small example project here (https://bitbucket.org/willgorman/avro-proto-test) with a test that recreates the error.  I've been able to do the same thing successfully using avro-thrift.  Is there anything that I'm doing incorrectly here?

Nevermind, I didn't realize that the first argument to the reader could be null.  Oops.
