We have a page on the two kinds of geometry implementations we have in the
system.
Streaming renderer works with JTS Geometry (implementing point, line,
polygon) which is an implementation of "Simple features for SQL".
The pint you created was an "ISO Geometry" which is an implementation of
ISO 19107.
If you could review this page of the documentation (
http://docs.geotools.org/stable/userguide/library/jts/geometry.html) and
construct a JTS Point instread your cdeo should work.
