   @Fokko I see the Spark tests are failing with this error
   ```
       java.lang.ExceptionInInitializerError
   
           Caused by:
           com.fasterxml.jackson.databind.JsonMappingException: Scala module 2.10.2 requires Jackson Databind version >= 2.10.0 and < 2.11.0
   ```
   
   This happens because Jackson expects `com.fasterxml.jackson.core` versions to match `com.fasterxml.jackson.module` and that doesn't seem to be the case here. I ran a gradle build scan and seems like `jackson-databind` version is being upgraded to 2.11 [because of Avro 1.10.0](https://issues.apache.org/jira/browse/AVRO-2853) which is causing this issue.
   [Gradle build scan link](https://scans.gradle.com/s/77u6s7hbyyqak/dependencies?configurationFilter=WyJ0ZXN0UnVudGltZUNsYXNzcGF0aCJd&dependencies=jackson&expandAll&focusedDependency=WzIxLDcsNzUsWzAsMCxbNl1dXQ&focusedDependencyView=versions&projectFilter=WyI6aWNlYmVyZy1zcGFyazMiXQ)
   
   I think we may need to bump Iceberg's jackson version in [`version.props`](https://github.com/apache/iceberg/blob/01fca3d0a3c5653fe5a4a2a88c29aeaffca33f1d/versions.props#L14) and in [`build.gradle`](https://github.com/apache/iceberg/blob/01fca3d0a3c5653fe5a4a2a88c29aeaffca33f1d/build.gradle#L97)
   
   @rdblue I am not a 100% sure if this is the right thing to do. I know Spark can be finicky about the Jackson version. Do you have any insights here?
