title: Eclipse intermittent "cannot be resolved to a type" error
body: <p>I keep running into a strange intermittent issue with eclipse for the past few days where I will be editing code, save it, and then eclipse starts reporting hundreds (or sometimes thousands) of <code>MyClassName cannot be resolved to a type</code> errors. The errors are completely bogus as the classes do exist, and if I do a clean and rebuild on the entire workspace the issue goes away. This is the second workspace in a row that it has suddenly happened to.</p>
  
  <p>Has anyone else ever run into this before? Is there some way to fix this issue without recreating an entirely new workspace (which is extremely frustrating). I'm not entirely sure what keeps happening to seemingly corrupt my workspaces.</p>
  
  <p>[Update]</p>
  
  <p>For clarification this is happening with multiple projects that are all Java (web application) projects using only the standard 'Java Builder.'</p>
