title: Stop at breakpoints only in certain thread
body: <p>I have some multithreaded code and am trying to set up some breakpoints in Eclipse so I can do some debugging.</p>
  
  <p>The breakpoint I want to set is in a class used by all of the threads. However, I only want the breakpoint to be hit when I am in the main thread. Is there a way to do this in Eclipse?</p>
  
  <p>I have tried to use the 'conditional' breakpoint options but cannot get it to work.</p>
