title: Eclipse - Execute Expression on at Point in Code?
body: <p>Is it possible to have Eclipse execute an arbitrary expression at a particular point in code when debugging?</p>
  
  <p>The Execute/Display functionality allows you to run arbitrary code in the context of debugging. A breakpoint stops flow.</p>
  
  <p>What I'd like is something like a breakpoint that can be inserted at a particular point in a class, doesn't suspend application flow, but instead executes a snippet of code.</p>
  
  <p>The background is I'm trying to debug some multithreaded code which I can't edit, and I want to do some naive <code>System.out.println</code>s to see when various things happen. If I use breakpoints then the flow of the events will be disturbed.</p>
