So trunk is now using jts-1.9-RC6 and has had no problems on the
GeoTools side of things.
Here is the code example that prompted the upgrade:
> static Geometry combineIntoOneGeometry( Collection<Geometry>
> geometryCollection ){
> GeometryFactory factory = FactoryFinder.getGeometryFactory( null );
>
> // note the following geometry collection may be invalid (say with
> overlapping polygons)
> GeometryCollection geometryCollection =
> (GeometryCollection) factory.buildGeometry( geometryCollection );
>
> return geometryCollection.union();
> }
Over on the udig side things were not so pretty; basically I found
another JTS fork where the buffer operation was
reimplemented to have a progress listener (mostly so operations could be
canceled). While this is a good ability to
have, and some JTS operations can take a very long time, the cost of
maintaining our own buffered operation is
a wee bit high. Suggestions are certainly welcome.
If you run into any problems, please send feedback early and often.
Feedback is why we were able to get early access
to this time around.
The wiki documenting this stuff has been updated a bit to.
