HCP: JAVA Runtime 51.0 vs 52.0

Hello!

Actually I am running the "Hello world" tutorial on HCP.

On my current eclipse I did create the WAR file and uploaded it in HCP.

When I am starting the App in HCP the following error occurs:

"HTTP Status 500 - helloworld/HelloWorldServlet has been compiled by a more recent version of the Java Runtime (class file version 52.0), this version of the Java Runtime only recognizes class file versions up to 51.0"

Does anyone know who I can "downgrade" my compiling in Eclipse?

Does anyone know when HCP will upgrade their JAVA?

THX
