title: Why is Guice throwing $ComputationException from UncaughtExceptionHandler in main?
body: <p>I'm trying to run an application that uses Guice and starts a Netty HTTP server. This is using Java 8.</p>
  
  <p>However, at startup I see this error in the console:</p>
  
  <pre><code>Exception: com.google.inject.internal.util.$ComputationException thrown from the UncaughtExceptionHandler in thread "main"
  </code></pre>
  
  <p>No stack trace, nothing else.</p>
  
  <p>What would be causing this error?</p>
