body: <p>Had the following error in Eclipse after installing Android 5.0 (SDK 21)</p>
  
  <pre><code>"Loading data for Android 5.0" has encountered a problem. 
  
  Parsing Data for android-21 failed  
  unsupported major.minor version 51.0
  </code></pre>
  
  <p>I am still facing the same problem on mac, and now as in the few answers try Java 1.8 where I found the latest version of it. Old is not available. 
  I already have updated Java but I don't know what's wrong with it.</p>
