title: Instance of an abstract class
body: <p>Couldy you clarify why this works:</p>
  
  <pre><code>public abstract class AbstractClassCreationTest {
  
      public void hello(){
          System.out.println("I'm the abstract class' instance!");
      }
  
      public static void main(String[] args) {
          AbstractClassCreationTest acct = new AbstractClassCreationTest(){};
          acct.hello();
      }
  }
  </code></pre>
  
  <p>I suppose it contradicts to the specification where we can find:</p>
  
  <p><strong>It is a compile-time error if an attempt is made to create an instance of an abstract
  class using a class instance creation expression (§15.9).</strong></p>
