Hi all

I'm having trouble getting Geoserver to recognise the SRS of EPSG:54009 TIFF + 
Worldfile data files. If adding a WorldImage store, the projection defaults to 
EPSG:40400. I can always force the SRS to be EPSG:54009 in the layer 
configuration if it's a single image, but I'm trying to build a mosaic and 
creating an ImageMosaic store fails with the common "could not list layers for 
this store" error.

I assume the unrecognised SRS is the problem here because the logs contain 
"GeoTiffMetadata2CRSAdapter::createCoordinateSystem:Only Geographic & Projected 
Systems are supported" when adding the imagemosaic store.

Any suggestions? Gdalinfo from the test file (below) seems OK and EPSG:54009 is 
defined in epsg.properties and appearing in the SRS list (also below):
