Hello,
I've never developed OpenJUMP, but I'm starting to use the Java
Conflation Suite (JCS) [0] which is dependent upon many JUMP classes,
and was started by Martin Davis (originator of JUMP and JTS as well).
JCS has not seen any (open) development since 2003, but it still
provides much of the functionality I'll need, and I'd like any
improvements I make to be usable for others. The application is a
plugin for JOSM [1], an OpenStreetMap [2] data editor, with an initial
goal to facilitate the conflating of "POIs" [3], such as upgrading the
geometry of a business from a point to a polygon, and merging the
attributes.

JCS depends on quite a few JUMP (circa 2003) classes, such as for
features and utility functions. I'd rather not have a dependency on
JUMP, but I'm not sure the best way to accomplish this, other than
pulling out all the required functionality and putting it in the JCS
package, com.vividsolutions.jcs. However if there's any changes that
should be made to the API, such as the Feature/FeatureCollection
classes, to make JCS more usable by other applications, I'd like to do
that now. Perhaps I should adopt some of the API from the Java
bindings for GDAL/OGR [4].

A while ago I put the two available versions of JCS in a Git
repository [5], which is where I'll be publishing any changes. I
posted a related query on the JTS list which is worth checking out for
those interested [6].
