I am sensing a push to move to JDK 1.5...
No real push, we are stuck at Java 1.4 until J2EE types have a migration
path ... however this does leave
us with the *cutover* technique, which was not much fun for CRS last year.
Aside: Any idea if Symbol or Symbolizer will be used in the future?
For now just going to update the geotools interfaces, and include GeoAPI
method names (where
they don't already match).

Well the first idea failed - we need Java 5 type narrowing to
pull it off.
The idea was:
- GeoAPI PolygonSymbol - unchanged
- GeoTools PolygonSymbolizer - extend PolygonSymbol
- GeoTools PolygonSymbolizerImpl - implement duplicated method
The obviously has conflicts as the two interfaces report back
different classes for Fill, and Stroke.
Performing the same change on Fill and Stroke is *still*
circular, without Java 5 there is no way for a GeoTools
PolygonSymbolizer to "narrow" the scope and indicate that
just a GeoTools Fill is returned.
So this technique could work, but would break all geoTools
renderers and client code.
Jesse points out that this could be handled with a
refactoring tool, but this is more work then our short term
goal justifies.
This experience will repeat itself Martin, every transition
to GeoAPI interfaces will be disruptive in nature until we
can assume Java 5 as a target.
