title: Eclipse JPA Project Change Event Handler (waiting)
body: <p>Why am I getting  'JPA Project Change Event Handler (waiting)', whenever I try to build my project.</p>
  
  <p>I have some JPA projects in my workspace and It takes lot of time to build my project. It also leads to GC over limit with 6GB of heap space allocated to eclipse</p>
  
  <p>I'm currently using Kepler. This issue did not occur in Helios.</p>
  
  <p>There are some BugZilla entries for the above bug, but I can see them fixed. But not available in 4.3.1?</p>
  
  <p>Any solutions/workarounds for the above issue?</p>
  
  <p>Thanks</p>
