The org.codehaus.jackson packages that are exposed as a third-party API in JAX-RS 1.1
are no longer exposed in the WebSphere Application Server Java Platform, Enterprise Edition (Java EE) 7 JAX-RS 2.0 and later implementation.
If you want to use any org.codehaus.jackson APIs in your application, you must package the Jackson packages with your application.
Review JAX-RS 2.0 behavior changes for more information on the code changes needed when migrating from JAX-RS 1.1 to JAX-RS 2.0 or later and using Jackson annotations.
When you are migrating from JAX-RS 1.1 to JAX-RS 2.1 on Liberty, it is recommended to first migrate from JAX-RS 1.1 to JAX-RS 2.0. In the binary scanner,
run the report with the --targetJavaEE option set to ee7 and resolve issues that are flagged
under the "JAX-RS 2.0" category.
