Yes, it is lagging.
I'm currently the main maintainer of the java code, and I heard about
the curve types when I read the postgis 1.2 announcement. :-)

The same for me, I'm afraid that the best documentation is the C code,
So, maybe, some documentation contribution (replacing doc/ZMSgeoms.txt
with a full featured EWKB description) is more important than the java
code, as all other client interface writers (python geotypes, qgis,
gdal etc.) depend on that documentation, too.

Just annonce that you're working on it on the postgis-devel list (to
avoid having several people working on the same issue), and then send
patches to that list.
I don't know of anyone else currently working on that issue.
Actually, there are several different open problems:
- Updating the org.postgis.* classes by adding the new geometry types
and tweaking the old ones (should be relatively straightforward)
- Updating the java2d mapping.
- Updating the JTS mapping. The main problem here is that, currently,
JTS does not support those extended types at all, AFAIK.
