Greetings all. I am trying out RESTEasy for the first time and having trouble getting it to run on Google App Engine (standard) with Java 1.7.

I tried 3.1.2.Final first, of course, but ran into the old "Unsupported major.minor version 52” issue. After looking around at the docs, release notes, blog, etc. it appears that Java 1.8 is the new target for builds as if 3.1.0.

So I backed off to 3.0.22.Final, but I’m seeing the same issue there.

What version do I need to fall back to gain Java 1.7 support?

Regards,

Kevin
