The easiest "fix" is probably to use the DefaultGeographicCRS.WGS84 pre-defined
constant instead. If
a custom GeographicCRS is still wanted but no BursaWolfParemeters object can be
supplied, then a
workaround is to use one of the following:
Hints hints = new Hints(Hints.LENIENT_DATUM_SHIFT, Boolean.TRUE);
CoordinateOperationFactory factory =
FactoryFinder.getCoordinateOperationFactory(hints);
CoordinateOperation op = factory.createCoordinateOperation(sourceCRS,
targetCRS);
or
MathTransform mt = CRS.transform(sourceCRS, targetCRS, true);
