The build server has been failing javadoc:aggregate target - but it is working locally!
Added to GitHub workflow - that works also
Update maven javadoc plugin - no change
Updated maven on build server - no change
Update Java on build server - thanks Torben that worked
Thanks for fix, not sure what the actual trouble was
Java 11.0.23 is now available as a selectable Java version for any config on the build server.
All three builds (geotools-30.x, geotools-31.x, and geotools-main) have been updated to use this version and are now confirmed working.
