title: IntelliJ 13.1.6 JDK 8 support
body: <p>I created a project that <code>Project SDK</code> set to <code>1.8 (1.8.0_25)</code>. The problem is that even <code>System</code> cannot be resolved, if I switched <code>Project SDK</code> to <code>1.7 (1.7.0_71)</code>, everything works fine. How to resolve this issue?</p>
