Hey all,

using this proto:  
`message foo {  
optional int64 f = 1;  
}

message boo {  
optional int64 b = 1;  
}

message aa {  
oneof bull {  
foo fa = 1;  
boo ba = 2;  
}  
required int64 b = 3;  
}`

and logstash config:  
`input { kafka { bootstrap_servers => ":9092" topics => ["logstash"] auto_offset_reset => "earliest" codec => protobuf { class_name => "Aa" include_path => ['/home/user/aa.pb.rb'] } } } output { stdout { codec => json } }`

I set aa.b to 128  
I recieved this output:  
`{"b":3104751,"@timestamp":"2017-05-23T13:53:09.756Z","@version":"1","ba":{"b":23}}`

If i set it to 127 it works, meaning I have an issue with the definition of int64, looks like it defines it like int8

libprotoc 2.6.1  
ruby-protoc 1.6.1

Do I need to compile the proto different?

Thanks!
