You must compile your project with Java SE 6, GAE does not support Java SE 7.
Here you see all informations about the Java environment.

Looks like Java 7 support has arrived as of last month. This have have cleared up the problem you were having.
"In App Engine 1.7.5, released in February of 2013, the Java runtime added optional support for Java 7 as an experimental feature. "
"In a future release, support for Java 6 will be removed, so it is a good idea to try running your existing Java 6-based app in the new Java 7 runtime while it is still optional."
