Jackson 2.3.x

Hi, when I was testing with Jackson 2.3.0 (jackson-jaxrs-json-provider) with bson4jackson 2.2.3 it is throwing the following error due to a class missing. By updating the version to 2.3.0 in bson4jackson build.gradle or excluding jackson-annotations from bson4jackson maven dependency it is working fine.
