PostGIS license (GPL) is mentioned in source bundle

[jmk75]

Why geolatte-geom source bundle (e.g. https://repo1.maven.org/maven2/org/geolatte/geolatte-geom/1.8.2/geolatte-geom-1.8.2-sources.jar) has PostGIS licensing related file /spatial_ref_sys_license? This is causing confusion in legal evaluations as it looks like this geolatte-geom library has PostGIS embedded as it's GPL license is mentioned:

"In general PostGIS may be distributed and/or modified under the conditions
of the GNU General Public License, either version 2 or (at your option) any
later version. Please refer to the COPYING file for details."

Can this be removed to avoid further confusion for legal people doing license evaluations for FOSS libraries?
