title: eclipse starts 'Building workspace' in endless loop
body: <p>Is it possible to debug which process triggered a 'Building workspace' in Eclipse?</p>
  
  <p>I have a Java project with some BIRT reports. While this project is open Eclipse restarts 'Building workspace' in an infinite loop.<br/>
  I'm using Eclipse 3.6.1 with BIRT 2.6.1</p>
