Title: Message Title

Łukasz Bocianiak created an issue   GeoServer / GEOS-9143 ImageMmosaic 2.13.3-2.15.0 transparent area overlaps with other geotiff making blank space Issue Type: Bug Affects Versions: 2.13.3, 2.15.0 Assignee: Unassigned Attachments: sample1.tif, sample2.tif Components: image mosaic Created: 09/Mar/19 1:11 AM Environment: Ubuntu 15.10 + JDK8 + Tomcat 8 + Geoserver 2.13.3 Ubuntu 15.10 / Ubuntu 18.04 + OpenJDK11 + Tomcat 9 + Geoserver 2.15.0 Priority: Medium Reporter: Łukasz Bocianiak Hi, this is a copy of: https://gis.stackexchange.com/questions/313758/geoserver-2-13-3-2-15-0-imagemosaic-blank-transparent-spaces-with-overlapping and http://osgeo-org.1560.x6.nabble.com/Geosrever-2-13-3-2-15-0-ImageMosaic-overlapping-transparent-from-alpha-band-td5397109.html 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.
