Do anyone know how to resolve Jetty ALPN not properly configured error, when I attempting to connect to Google Cloud BigTable?

I needed to add a VM option for Jetty alpn-boot. 

 -Xbootclasspath/p:C:\Users\cleuer\.m2\repository\org\mortbay\jetty\alpn\alpn-boot\8.1.3.v20150130\alpn-boot-8.1.3.v20150130.jar

This error occurs when netty jar version is mismatched with other jars.

If you received an error message "ALPN is not configured properly" or "Jetty ALPN/NPN has not been properly configured", it most likely means that:

1) ALPN related dependencies are either not present in the classpath

2) or that there is a classpath conflict

3) or that a wrong version is used due to dependency management

4) or you are on an unsupported platform (e.g., 32-bit OS).

Please see gRPC troubleshooting guide https://github.com/grpc/grpc-java/blob/master/SECURITY.md#troubleshooting.

Hope it helps.
