Sigh, back in GeoTools ReprojectingFeatureCollection is eatin the original
exception at line
131
The reason why it's throwin an exception is that a few lines ago the code
is not asking for
a lenient transformation, and the referencing code throws this:
public static void main(String[] args) throws Exception {
CRS.findMathTransform(CRS.decode("EPSG:25832"),
CRS.decode("EPSG:31251"));
}
Exception in thread "main"
org.opengis.referencing.operation.OperationNotFoundException: Bursa wolf
parameters required.

The code should simply be:
CRS.findMathTransform(CRS.decode("EPSG:25832"), CRS.decode("EPSG:31251"),
true );
instead. The fix is easy, but someone has to write a test before it can be
committed.
Do you have a checkout of GeoTools and time to look into it?
Cheers
