GTiff with colour table quality issue.

GeoServer - User mailing list

Hi List,

 

I have just set up two identical new Geoserver instances on two separate servers.

 

Windows Server 2012

OpenJDK 12.0.1 with server JVM (x64)

Tomcat 9.0.19 (x64)

Geoserver 2.15.1 with JAI-EXT and marlin 0.9.3

 

I have some coverage layers on each server made up of identical files copied from one server to the other.  The image tiles produced by the TEST server are crisp and clear.  The identical tiles produced by the LIVE server are pixelated and discoloured.  See attached images.

 

Source images are created as uncompressed GeoTIFFs with JPEG overviews, with XML stats and PRJ files for each tile.  The only thing I can see is that it is the GeoTIFFs with a colour table returning the mangled images but only on the LIVE server – the TEST server is fine.

 

Am I missing some configuration setting or is there something in the data directory affecting things?  Is it my JVM?

 

Any pointers much appreciated

 

Ross

Oh wow, GeoServer actually runs on JDK 12? It's like the first installation I hear about.
Mind, 2.15.x is built and tested with java 8 and java 11, most installations I know about are running a OpenJDK 8 (which unlike Oracle JDK is still supported and getting releases, see for example https://adoptopenjdk.net/)
 

Tomcat 9.0.19 (x64)

Honestly I don't know, but, you say the data is the same... is the configuration too? Is the JDK a 12 in both cases?
