Spring MVC + Dandelion Datables Exception starting filter dandelionFilter

In my Spring MVC application I have used Dandelion Datatables 0.10.1, due to some performance issues I have decided to upgrade the version to 1.0.1 following the official migration guide from:

http://dandelion.github.io/components/datatables/1.0.0/docs/from-0.10.x-to-1.x.html

I have included all the required Maven dependencies, configured the web.xml accordingly to use also the Servlet 3.0 version but when I try to run the appplication I get the following exception during the dandelionFilter loading. Any help is appreciated.

The strict duplication detection feature was added in Jackson-Core 2.3. See http://fasterxml.github.io/jackson-core/javadoc/2.3.0/com/fasterxml/jackson/core/JsonParser.Feature.html#STRICT_DUPLICATE_DETECTION

If possible, you should update this dependency to v2.3.x minimum.
