title: Peculiar Eclipse java.lang.UnsupportedClassVersionError, Unsupported major.minor version 52.0
body: <p>First of all, I'd like to point out that I <em>am</em> aware that this question has been asked countless times and I am aware of the usual solution. However, it doesn't seem to work for me.</p>
  
  <p>When the error <code>Exception in thread "main" java.lang.UnsupportedClassVersionError: org/telegram/mtproto/state/ConnectionInfo : Unsupported major.minor version 52.0</code> occurs, it is generally caused by compiling with an incompatible JDK-JRE combination. However, as shown by the images below, my setup seems to be in order:</p>

  <p><strong>What seems to be the problem? What am I missing?</strong> I'm using <strong>Eclipse Luna</strong>, trying to run some <strong>Telegram API</strong> Layer 11 code (the code works I reckon, as it was used by others).</p>
