Hi,

I added java-dogstatsd-client 2.6.1 to my Java 1.8 project using Ivy + Maven and then configured the client to send metrics via Unix socket. The project compiled successfully, however I started getting a bunch of runtime errors related to JFFI. I don't have all the stacktraces unfortunately but there were things like:

LoadError: Could not load FFI Provider: (NotImplementedError) FFI not available: null

Finally, after some trial and error, what solved it for me was adding this dependency explicitely:

<dependency org="com.github.jnr" name="jffi" rev="1.2.18"/>

and then also adding jffi-1.2.18-native.jar manually since Ivy was not pulling it correctly for some reason.

So I think the dependency on JFFI should be either explicitly added to the POM or at least documented in the README.

Looks like java-dogstatsd-client correctly specifies its dependency on jnr-unixsocket 0.18 which in turn depends on the stuff that caused me problems. So I think
it might not be an issue with java-dogstatsd-client itself but probably with the way jnr-unixsocket dependencies are specified or with my project setup.
