Hi,

thanks for the new release! We have noticed a problem though, that deals with 
environments where GeoTools (and now ImageN) and JAI are used at the same time. 
I have documented the issue at 
https://github.com/eclipse-imagen/imagen/issues/118 and there is a PR attached 
https://github.com/eclipse-imagen/imagen/pull/119. 

I wonder if there's any chance the problem can be solved soon as it currently 
prevents us from upgrading to GeoServer 2.28.x. 

Thanks and Best Regards
Sören

  of the latest stable version of GeoTools 34.0 
<https://ofcsg2dvf1.dwd.de/fmlurlsvc/?fewReq=:B:JVE3PDg8Nyt7MD8jPStkaTA9PDc9PCt+ZGpjbHl4f2gwbDU1azU5OWhpaT9sbG5rPTRuPmw9ND9rOWg7NGhuPDU9Oz88aWtsOit5MDw6Ozw8ODQ1OjsrfGRpMDg0QEc5bGFpPT85NDs4IDg0QEc5bGFoPT85NDs4K39ufXkwXmJof2hjI0ZsYWh+fmhNaXppI2loK24wOD8rZWlhMD0=&url=https%3a%2f%2fsourceforge.net%2fprojects%2fgeotools%2ffiles%2fGeoTools%252034%2520Releases%2f34.0%2f>
 . This release is available from the repo.osgeo.org 
<https://ofcsg2dvf1.dwd.de/fmlurlsvc/?fewReq=:B:JVE3PDg8Nyt7MD8jPStkaTA9PDc9PCt+ZGpjbHl4f2gwbGw0Pms+O2g7NDs/aD84NT47PjloPj48O2g6PGw7OGxpbDg+aG44byt5MDw6Ozw8ODQ1OjsrfGRpMDg0QEc5bGFpPT85NDs4IDg0QEc5bGFoPT85NDs4K39ufXkwXmJof2hjI0ZsYWh+fmhNaXppI2loK24wOD8rZWlhMD0=&url=http%3a%2f%2frepo.osgeo.org>
  and is made in conjunction with ImageN 0.9.0, ImageIO-Ext 2.0.0, GeoWebCache 
1.28.0, and GeoServer 2.28.0.

This is a major update:

*       The library now requires Java 17, ending support for Java 11
        
*       Upgrade from Java Advanced Imaging Library 1.1.3 to Eclipse ImageN 
0.9.0.
        
*       Library now provides a maven bill-of-materials import for both library 
modules and third-party-dependences making it considerably easier for 
downstream projects to synchronize dependences when upgrading GeoTools
        
*       For more information please see upgrade instructions

Thanks to Jody Garnett (GeoCat) for making this release, Gabriel Roldan 
(Camptocamp) for all the build improvements, and Andrea Aime (GeoServer) for 
working so hard on the Eclipse ImageN migration.

These major library updates were undertaken as part of the GeoServer 3 
activities, and we would like to the crowdfunding sponsors their financial 
support.
