I am migrating a JAX-RS application from WebSphere 8.0 to WebSphere Liberty 8.5.5.

In WebSphere 8.0, Jackson was provided by WebSphere. I can find `jackson-core-asl-1.9.12.jar`, `jackson-jaxrs-1.9.12.jar`, `jackson-mapper-asl-1.9.12.jar` and `jackson-xc-1.9.12.jar` files in the `AppServer\plugins\` directory.

In the new application server (WebSphere Liberty), I get the following exception: `org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "myPropertyName"`. I think that this exception happens because the annotation `@JsonIgnoreProperties(ignoreUnknown = true)` on the serialized classes does not work. My guess is that it happens because WebSphere Liberty 8.5.5 provides an older version of Jackson.

I tried to deploy the version of Jackson which I need with my application,
but it did not help (I still have exceptions). How can I make WebSphere Liberty use the version of Jackson that I need?
