Re: [Geotools-devel] Shapefile editor/renderer and shapefile locking

[LSA <ls...@ng...>]

I have created sample code reproducing the issue.

Here is the source:
http://sites.google.com/site/lattati/downloads/ShapeRenderer.java?attredirects=0&d=1
Sample shapefile (required to repproduce):
http://sites.google.com/site/lattati/downloads/RUS_rds.zip?attredirects=0&d=1
Exception log:
http://sites.google.com/site/lattati/downloads/exception.log.txt?attredirects=0&d=1

One will need to download the source and data, place data 
somewhere and change the variable
private static String DATA_PATH = 
"c:/temp/data/RUS_roads.shp";

In order to reproduce, one can click on "Change data" 
button.

Then one can obtain exception log like one mentioned 
before.

Still hoping someone will explain for me what is wrong 
with my code...

Thanks,
Sergey
