We have had a good result from the code sprint folding in all the functionality from https://github.com/geosolutions-it/mapfish-print fork into https://github.com/mapfish/mapfish-print-v2 and having it build with Java 11 and the GeoTools API change.

The net result is that GeoNode should be usable with the out-of-the-box geoserver-2.24.x-printing-plugin.zip. Indeed if you download a nightly build you could confirm this for us.

We would like to make sure you are happy before making the GeoServer 2.24.0 release.

@jodygarnett we're going to test the new mapfish print soon
