Summary: ArcExplorer not able to read Shapefiles

Initial Comment:
I work with research vessels (ships). While trying to
utilise geotools to generate shapefiles of vessel track
for use with mapserver (http://mapserver.gis.umn.edu/)
it became apparent that the shapefiles generated by
geotools could not be read by mapserver.  The idea is
to generate an updated vessel track every 5 min as the
vessel steams along.  The shapefile trying to be
generated contains a single line with 1000's of points
(5 minute vessel track - 288 points per day * 3 months).  

Further experimentation revealed that the shapefiles
generated could be read and displayed by esri's arcview
but not by esri's arc Explorer product.  If the
generated shapefiles where saved from arcview, they
could be viewed from arcview, arc explorer and mapserver.

I then reduced from a few 1000 points to a couple of
points. The differences between the generated shapefile
and the one saved by arcview was only a few bytes. I
attempted to compare with the esri shapefile specification.

Attached is the conversion

I have had a bit further of a look.
I have found the problem and fixed, is it possible
to include in geotools.

Attempted with geotools 0.8.0 but no luck.
Also tried with latest version of ArcExplorer (Java version) 
version 4.

The arcExplorer I am trying to use is 3.1 (java version).

Files attached in a zip file are
a. the .java for the conversion I am trying to do
b. the .txt data file I am trying to convert

I'd like to look into this can you try attaching the files
again. 
I must confess to only having tested the shapewriter code
against arcview. Since I have a unix box I don't have
arcexplorer on my machine.
