I am getting the below exception when running the sample "speech" application as a plain java application. I have not run it on any server as of now.

Sample application can be found at- https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/speech/cloud-client.

Exception in thread "main" java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.

I have tried most of the steps provided over the net but no luck. It uses google cloud speech version - 0.20.3-alpha. I have also tried with google cloud speech version -0.17.1-alpha but same issue.
