There is one single difference. In the old (working) system the WKT used
Oblique_Mercator where the newer ones use Hotine_Oblique_Mercator.
So what should I do? How can I override this definition? And can I update
the version in Geotools somehow?
In other project I have added a epsg-property with a properties file with
only the single definition. But I am never confident which version will be
used, the epsg-property or the hsql definition.
