title: Unsupported Java Version: Cannot start under Java 1.7: Java 1.8 or later is required
body: <p>I just updated to <code>IntelliJ IDEA 16</code> which comes with <code>Java JDK 1.8</code>. Fyi, I had downloaded Java JDK 1.8 a long time ago.</p>
  <p>I tried to run my plugin that I am developing, and I cannot even do that, I get the following error message (slightly condensed)</p>
  <blockquote>
  <p>&quot;C:\Program Files\Java\jdk1.7.0_45\bin\java&quot; -Xmx512m -Xms256m -XX:MaxPermSize=250m -ea &quot;-Xbootclasspath/a:C:/Program Files (x86)/JetBrains/IntelliJ IDEA Community Edition 144.3143.6\lib\boot.jar&quot; -Didea.config.path=C:\Users\Christopher.IdeaIC14\system\plugins-sandbox\config - ... -Dfile.encoding=windows-1252 -classpath &quot;C:\Program Files\Java\jdk1.7.0_45\lib\tools.jar; ... ;C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 144.3143.6\lib\idea_rt.jar&quot; com.intellij.rt.execution.application.AppMain com.intellij.idea.Main</p>
  <p><strong>Unsupported Java Version: Cannot start under Java 1.7.0_45-b18: Java 1.8 or later is required.</strong></p>
  </blockquote>
  <p><strong>So, I clearly know what the problem is; however, I cannot seem to figure out where the location to fix this is.</strong></p>
  <p>I have tried a lot of things so far; most involve using the <strong>search box</strong> in <code>Settings</code> and switching whatever I could to version 1.8. Also, I had updated my <code>Environment Variable</code> for Java from 1.6 to 1.8</p>
  <p>With all of these changes, nothing is working! So how do I go about fixing this seemingly simple issue?</p>
