title: Breakpoints in Eclipse stopped working
body: <p>I was coding late yesterday (might be important) and debugging and breakpoints were working fine.</p>
  
  <p>Today, probably when I pressed some unknown shortcut, execution is not stopping on breakpoint.</p>
  
  <p>First thing I noticed is strange icon:</p>
  
  <p><img src="https://i.stack.imgur.com/TPkgm.png" alt="enter image description here"></p>
  
  <p>but I found no option (basically because I do not know what I'm looking for) to switch it back...</p>
  
  <p>Currently it is crossed (I do not know what is that) but it is not disabled (icon is empty in such cases).</p>
