App Engine support?

[achuinard]

Any chance this works on App Engine under the Java 8 runtime? If so should the README be updated? I can create a PR for the README if @danfickle says it runs.

Java 8 has no restrictions so it seems like it would run on App Engine...

Thanks @achuinard

I've changed the readme. I'll leave this issue open until someone has confirmed that it works.

Yep, it works. No issues yet. Java App Engine Standard Environ 8.

It does works, but I also got this on the first call, subsequent call on the same instance works fine tho.
