body: <p>I am a little confused.</p>
  
  <ol>
  <li><p>Oracle says Java 8 is highly compatible with Java 7 (backward). But, what possibilities exist that Java 8 program can be run on Java 7 successfully (SE/EE)?</p></li>
  <li><p>If point one was true, Java 8 applications will be deployed and executed on a Java 7 server support? for example, Tomcat 8 or WildFly?</p></li>
