Creating protobuf.Message

[Omid]

Hi, I'm trying to use ScalaPB with another library that has functions that use Message as the input and output. Here is the example used in the Java lib here.

I need a way to cast classes that I have generated using ScalaBP to com.google.protobuf.Message so I can work with this lib. 

I checked the Java conversion but I cannot find a way to get the same results. Any help is appreciated. 

Thanks
