Using google-cloud-speech:0.35.0-alpha

[avinashmeda]

Forgot to mention its on windows 10 . java version : 1.8.144

@avinashmeda I think this is a common issue on Windows. You might wish to search other issues. If memory serves, it has to do with /tmp being writable. But do look to find an authoritative answer.

@nnegrey PTAL

Quick search till I can dig in more, but I believe most of the ALPN issues are on this repo (did a quick search) https://github.com/GoogleCloudPlatform/google-cloud-java/search?utf8=%E2%9C%93&q=ALPN&type=Issues

https://github.com/GoogleCloudPlatform/google-cloud-java/blob/master/TROUBLESHOOTING.md should help.
