This looks like a jar version issue. The JCS codebase is a few years
old, and hence needs an older version of JTS to run. I'm not sure what
that version actually is, but the site you got JCS from in the first
place whould tell you.

Thanks Martin,
I exploded all the multipart polygons and ran it again, however I get a

duringBoundary Match
It's been quite a while since I wrote this, but I believe that Boundary
Matcher was coded to work only with Polygons, not MultiPolygons. Try
exploding all MPs in your dataset.

Hi,
Brand new user here.
I'm, trying to boundary match boundaries of a number of polygons in
one
coverage to another coverage with more precise boundaries and I'm
getting the following error:
java.lang.ClassCastException:

If somebody can give me an idea as to what the problem is I would
greatly appreciate it.
Also, can someone give me a little more info on the distance tolerance
(units?)
Thanks in advance!
