Upgrade Jackson version to latest patch (or later minor version)

[cowtowncoder]

This is more of a minor request for maintenance, not bug per se, but I noticed that the project has a dependency to rather old patch version of Jackson, 2.4.3.
Since newer versions typically contain many bug fixes, I would suggest dependency upgrade.
The safest option would be simply to use latest 2.4 patch, 2.4.6:

http://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind

but it might make sense to consider an upgrade to a later minor version as well.
This could help with transitive dependencies as well since most frameworks these days rely on Jackson 2.8, 2.8.9 being the most "popular" patch version (and 2.8.10 latest)

Thanks for pointing out @cowtowncoder, coming from Jackson maintainer, we'll take the advice seriously! :)

@merlimat No prob -- let me know if I can help. I have some vested interest here too, many co-workers are actually evaluating use of Pulsar, lots of excitement. So really wishing all the best with development, hoping to learn more myself.
