Not many people need to compile the whole Vaadin JAR from sources (often you can just copy a single class to your project and modify it if necessary), but if developing Vaadin core:

Vaadin 6 has and will retain Java 1.5 compatibility, while Vaadin 7 (since alpha 3) requires at least Java 1.6.

The support for 1.5 is there because there are still application server deployments around that do not support 1.6 and get upgraded slowly so we have made a policy decision to continue supporting it for the whole Vaadin 6 series. At least we don't get requests to support 1.4 anymore...

You can use the property "ignoreversion=1" to make the build script ignore the real version of JDK in use and accept JDK 1.6 or 1.7.
