This error will occur when one compiles the Java program using JDK 1.8 and deploys to app engine. The project works fine in the local server, but we get this error while deploying.
Quick Solution:
If you have Java 1.8. Let it be, but also install Java 1.7 and make the changes in the Eclipse as shown below. Also if you are using JSP pages in your project, make sure to check JDK instead of JRE in "Installed JRE's"
I have uploaded the project to app engine without any errors and it works. You can check that here
http://acquitworld.appspot.com/ . I have worked a lot on App engine in the past week so I got to know lot of work around for many errors which will come in the way. So, feel free to ask me. I will be able to help you.
