title: Netty exception handling - Handler throws Exception, then what?
body: <p>I've searching around for an exception handling pattern for Netty but I'm not able to find much. </p>
  
  <p>Some sort of exception handling guide would be great. I have exceptions thrown that are sent to exceptionCaught but I don't know what to do next. </p>
  
  <p>Can someone provide a general purpose explanation of how to handle exceptions in Netty. What is the expected pattern for handling an exception thrown from a ChannelHandler?</p>
  
  <p>Thanks,
  Matt</p>
