title: Default JDK used for android studio when STUDIO_JDK is not set
body: <p>I am building a plugin for Android Studio using IntelliJ but it always shows this error when I try to load it on Android Studio. Unless I set STUDIO_JDK to the jdk1.8 path.</p>
  
  <pre><code>com.intellij.diagnostic.PluginException: MyComponent :
  Unsupported major.minor version 52.0
  </code></pre>
  
  <p>So I wonder what JDK will android studio pick up by default when STUDIO_JDK is not set.</p>
