How well does this play together with AppEngine 1.7.7? From their release notes: "The Java runtime now defaults to Java7. If you still need to use the Java6

It sounds I should compile for a 1.7 target. So I should *not* set maven.compiler.source to 1.6, right?

I don't know how AppEngine's Java runtime works, but my 7 and 8 JREs are very well capable of running classes compiled with -target 1.6 or earlier, and mixing classes compiled with different -target (you'd never be able to use Maven, or pretty much any third-party dependency actually, if that wasn't the case; btw GWT is compiled with -target 1.6 and is fully compatible with a JDK 7, and we haven't yet heard of anyone having issues using RPC or RequestFactory on AppEngine)
