issue with GetCoverage requests against S2 and L8 mosaics

[randomorder]

I am experiencing and issue with requests found in OGC links for Sentinel2 and Landsat8 that needs investigation. And example of such request would be:

http://cloudsdi.geo-solutions.it/geoserver/geosolutions/LANDSAT8_MOSAIC/wcs?service=WCS&version=2.0.1&coverageId=geosolutions__LANDSAT8_MOSAIC&request=GetCoverage&format=geotiff&subset=http://www.opengis.net/def/axis/OGC/0/Long(34.57896,36.97735)&subset=http://www.opengis.net/def/axis/OGC/0/Lat(32.10134,34.17715)&scaleaxes=i(0.001),j(0.001)&CQL_FILTER=eoIdentifier=%27LC08_L1TP_174037_20170731_20170811_01_T1%27

Resulting in the following exception:

java.lang.IllegalArgumentException: colorModel == null! colorModel == null!
