Animal sniffer provides tools to assist verifying that classes compiled with a newer JDK are compatible with an older JDK. This integratesthe latest version of the tool (1.11) that permits the use of custom annotations. Added @UsesJava7, @UsesJava8 and @UsesSunHttpServer and annotated the few places where we rely on a specific environment. The verification process can be invoked by running the 'sniff' task.
