Update the samples and integration tests to use Java 8. There's no
specific reason to keep them on Java 6 and it helps keep Eclipse happy
if we upgrade.
Given that Spring Boot uses java config accross the board, a new `value`
attribute is now aliased to the existing `classes` attribute such that
one could write the following:
@SpringApplicationConfiguration(MyConfig.class)
public class MyTest {}
Closes gh-3635
Undertow’s WebSocket client sends an illegal Origin header – it does
not include the scheme, e.g. it’ll send “localhost” rather than
“http://localhost”. This commit works around the problem by allowing
access to the SockJS endpoints from any origin, thereby disabling
OriginHandlerInterceptor’s checking of the Origin header.
