[Geoserver-users] Geosrever 2.13.3-2.15.0 ImageMosaic overlapping transparent from alpha band

Hi All,

I'm migrating from OracleJDK1.7/Geoserver2.8.3 to OpenJDK11/GeoServer2.15.0,
and have issues with ImageMosiac layers. In short words - can't configure
two geotiffs to glue together where they overlap.

Tried and searched everything, installed 10 versions of Geoserver and
figured out it stopped working in Geoserver 2.13.3 (GeoTools 19.3). In
GeoTools release notes I found that some transparency issues were fixed
then, but it stopped working for me.

I understand that I have alpha band in my files, not "no data" so popular
problems with no-data and enabling JAI-EXT, setting transparency color is
not the problem/solution.

It works fine with no configuration (just clean geoserver install, create
store and publish layer, only set names) with JAVA8 / Geoserver 2.8.3,
2.12.5., 2.13.0, 2.13.2 but not 2.13.3 and next releases.

Here are details and samples:

Hi Lukas,
can you open a ticket at https://osgeo-org.atlassian.net/projects/GEOS/summary
and attache the tiff files there? I don’t know about others, but I’m not particularly eager
to give my mail address to random web sites

Cheers
Andrea

Hi Andrea,

Thank you for your response. You have right, that was not the best site I could upload the files with, I updated it with direct download

And created the ticket and attached files at https://osgeo-org.atlassian.net/browse/GEOS-9143

Try disabling “Tile Recycling” under Settings/Image Processing.

I had a similar issue on a 2.12.5 instance recently and that fixed it.

Thank you, I checked the option and it is unchecked (by default I think), changing it doesn’t help

I tested the 2.12.5 version earlier and it works properly in my case with clean install of Geoserver, it breaks after 2.13.2
