Thanks! You answered this question over a year and a half ago, but I just
hit this very problem while converting an app from 2.7.0 to 2.8.2. (Why
now? With Oracle cutting off Java 8, we moved to Amazon Corretto, and found
some old imaging stuff that would not work with OpenJDK. As long as I was
correcting this and moving from Java 6 to OpenJDK 8--and with this weeks
Canary problems in mind--I decided to bump GWT as well.)
Interesting what you say about Jetty in 2.7.0: I've never had a problem
with Servlet spec 2.5 and GWT 2.7.0 (this app has used 2.5 for years).
>From my testing with Tomcat 8.5, I can still use servlet 2.5 or 3.0 in the
web.xml header of the deployed app. Have you seen issues in deployment? I
ask because we've one customer who runs WebLogic and their current
version--12.1.3.0.0--only supports up to 3.0.
