Twill is not working with netty 3.10.5
I recently tried running Fluo with the latest version of Zookeeper, which
brought in a newer version of netty. For an unknown reason this newer version
of netty causes the Twill application master to not work. I constantly see
errors like the following when trying to start a Fluo applications.
```

There are no errors in the Twill AM log. If I put netty 3.9.9 high on the
classpath OR use an older version of zookeeper (which has an older version of
netty), then everything works ok.
I also tried netty 3.10.6 and experienced the same problem.
