title: Eclipse debugging is not working
body: <p><img src="https://i.stack.imgur.com/BqLjl.png" alt="enter image description here"></p>
  
  <pre><code> Eclipse IDE for Java Developers
  
  Version: Luna Service Release 2 (4.4.2)
  Build id: 20150219-0600
  </code></pre>
  
  <p>I put some breakpoints in this first picture:</p>

  <p>After that, i clicked the bug symbol to start debug mode:</p>

  <p>But the application started as if it is in normal run mode. And as you can see in 2. picture, those buttons can not be clicked (next step, step into).</p>
  
  <p>I was using kepler, it was same so i downloaded luna but it is still same. I could use debug mode 5-6 months ago. I did not use eclipse since that time and did not change anything.</p>
