title: toString() unavailable error in Eclipse debugger
body: <p>While stepping through a method using the Eclipse debugger, I started seeing "toString() unavailable - no suspended threads" for all the variables I wanted to inspect.</p>
  
  <p>Why did I get that error, and what should I do next to narrow down the problem in my code?</p>
  
  <p><strong>edit</strong> My code does create a new process, but the variables I wanted to examine exist in the main application thread, and that thread didn't appear dead (in the Debug panel or the Console).</p>
  
  <p>I'm using Eclipse 3.4.</p>
