title: How to use "Infer Generic Type Arguments..." in Eclipse
body: <p>Whenever generics are missing from source code in eclipse it suggests I "Infer Generic Type Arguments..."</p>
  
  <p>The problem is that I don't think "Infer Generic Type Arguments..." has ever actually inferred anything. It typically comes up with no suggestions.</p>
  
  <p>What scenarios does it work for? How does it work? </p>
  
  <p>There have been a few cases where it is possible to "infer" something - eclipse still comes up blank.</p>
