6 years ago 1) for me I could solve similar issue using jetty-alpn-agent jar - see my reproducable codebase here - https://github.com/upd-machine/nlu-pipeline/issues/1 (I am using against google-dialogflow though)
wget http://central.maven.org/maven2/org/mortbay/jetty/alpn/jetty-alpn-agent/2.0.7/jetty-alpn-agent-2.0.7.jar
java -jar -javaagent:jetty-alpn-agent-2.0.7.jar nlu-intent-toolkit.jar agent1 "where is porcupine tree playing?" credentials.json But that is not a prod ready code so i m not sure if that's the best way i will fix it. This might be helpful - https://github.com/grpc/grpc-java/blob/master/SECURITY.md#tls-with-jdk-jetty-alpnnpn
2) ALSO, their google-cloud-compat-checker might be useful. Its bit painful to use it because they use parent versions. I don't understand why dont make it a jar that can be used anywhere.
the compat-checker tells if you have ALPN supported in your environment, example,
$ mvn exec:java

Your environment is not supported by Forked Tomcat Native.
See http://netty.io/wiki/forked-tomcat-native.html for details.
This means that you won't be able to use grpc-based APIs, but
http1-based APIs should still work.

Although I've seen similar issues, they all seem to be closed, I'm still seeing the following error with recent versions of this API. Related to: https://github.com/GoogleCloudPlatform/google-cloud-java/issues/2740 https://github.com/GoogleCloudPlatform/google-cloud-java/issues/3036
My test program is doing the following:
Here's my maven pom.xml dependency. Dependency tree attached:
Any idea what I'm doing wrong? Can I even run this outside of the Google network? Please excuse the obvious ignorance of this stuff.
