Jackson requires an upgrade because there is currently a bug in Avro due to it (I ran into it in
AVRO-1325, unit tests there fail without Jackson 1.9.12.
Hadoop1: I am not sure what the best version here is – 0.20.205 feels a bit old. Suggestions?
Jopt-simple is a low risk update.
Paranamer is a low risk update (only a handful of bugfixes).
sfl4j looks safe to update (performance improvements, bug fixes, and now compiled against Java 1.5 target).
Junit is safe to update.
netty – netty 3.6.6.GA should be compatible (see http://netty.io/news/index.html) and has many fixes / enhancements.
(an aside, netty now supports HTTP, so perhaps we can drop the ancient Jetty version we use and rely on netty for both raw and http to simplify things later?)
The remainder are plugin updates, which are generally safe since testing them is easy to cover.
I'll submit a patch with the updates shortly.
