[gdal-dev] Building java bindings with GDAL 2.1.3

[Even Rouault]

Paolo,

Yes much likely this error is typical of a mismatch between SWIG 1.3 and SWIG 2 or 3. It is 
likely that the gdal.jar in GeoServer was produced with SWIG 1.3, so you'll need to 
generate the native part (libgdalconstjni.so, etc...) with SWIG 1.3 as well (you can build it 
easily from source, ./configure --prefix=$HOME/install-swig-1.3; make; make install and 
then put $HOME/install-swig-1.3/bin in top of your PATH, before building again the GDAL 
Java bindings). Or you may try to replace the gdal.jar located somewhere in the geoserver 
installation with the one you've generated with SWIG 3.
But in both cases I'm not completely sure that things will work due to a few (subtle) 
changes in the GDAL Java API between GDAL 1.x used by this old GeoServer and GDAL 2. 
Depends if GeoServer uses those API.
