Bigquery Datatransfer and Redis use GRPC but set language level to 1.7

What's the problem with this?

[elharo]

My understanding was that gRPC required Java 1.8.

gRPC requires Java 1.6. https://github.com/grpc/grpc-java/blob/master/build.gradle#L57

[elharo]

Maybe I'm thinking of the App Engine environment. I think the java7 runtime didn't support grpc, but maybe that was a result of the whitelist, not the JDK.

That's correct. I'll go ahead and resolve this now.
