title: One line Hello World java project, Socket operation on nonsocket: configureBlocking
body: <p>First got this error with Eclipse Neon. Installed Oxygen and get the same error. Under Oxygen, I created a new Java project with a one line Main function to write "Hello, World!":</p>
  
  <pre><code>/**
   */
  package com.brindlewaye.hello;
  
  /*
   * author Dave
   */
  public class Hello {
      /*
       */
      public Hello() {
          // TODO Auto-generated constructor stub
      }
  
      /*
       * @param args
       */
      public static void main(String[] args) {
          // TODO Auto-generated method stub
          System.out.println("Hello, World!");
      }
  }
  </code></pre>
  
  <p>Same error.</p>
  
  <p>I have searched and found nothing that applied, IMHO, to a simple one line, Hello World, Java project.</p>
  
  <p>What might the problem be?</p>
