-------------------------------
.015 Removed mentions of unused (for now) shaded-netty; was messy us up when
building on Unix (classloader if I were to guess).

> Currently we are using guava 12.0.1, but the latest version is 21.0.
> Upgrading guava is always a hassle because it is not always backward
> compatible with itself.
> Currently I think there are to approaches:
> 1. Upgrade guava to the newest version (21.0) and shade it.
> 2. Upgrade guava to a version which does not break or builds (15.0).
> If we can update it, some dependencies should be removed:
> commons-collections, commons-codec, ...
