No PointSymbolizers are rendered when Shapefile resides in a JAR. 
------------------------------------------------------------------

                 Key: GEOT-1958
                 URL: http://jira.codehaus.org/browse/GEOT-1958
             Project: GeoTools
          Issue Type: Bug
          Components: core render
    Affects Versions: 2.4.4
         Environment: Reproduced with Linux and Windows, Java 1.6.0_07, GT 2.4.4
            Reporter: Stefan Alfons Krüger
            Assignee: Jesse Eichar
            Priority: Critical


No PointSymbolizers are rendered in the JMapPane when the Shape resides in a JAR.

 This only occures since GT 2.4.4. A workarround is to switch the gt2-render-2.4.4.jar  against gt2-render-2.4.2.jar. Then all works fine again.

I access the data by creating a DataStore from an URL that i get via a 
ClassLoader... In the "JAR scenario" these URLs point to a .shp in a JAR... 

When i pack the data in JARs i can start the application, but NO PointSymbols 
are rendered! Line and Polygone are rendered. When I pack it in JavaWebStart 
also no PointSymbols..other geometrys are all renderd. TextSymbolizers for 
the points are rendered.

No exceptions are thrown!

1. I am sure, that the SHP files are imported successfully and the SLD is 
imported successfully.
VIa debugging I checked that the correct Style-Object exists in the MapLayer during 
runtime and i can click the invisible points with my "info" tool. So 
the data and styles are loaded in the MapContext. 
Even the graphics.draw(..) method is executed in the ShapePainter...java class. But i don't see any 
points in the map!

When i simply unzip the data jars and put the direcory into the classpath (instead 
of the JAR) it works fine.

It did try different PointSymbolizers .. i am trying it with most simple MARK 
graphics at the moment. But as mentioned above... it works as soon as i 
unpack the JAR or switch back to gt-renderer-2.4.2.jar

So if anybody has any ideas why the PointPymbolizer breaks or acts differently 
in the JAR scenario with 2.4.4... 

I looked at the differences in the code between gt-renderer-2.4.2.jar and gt-renderer-2.4.4.jar but i didn't find anything that could explain the problem.

I think this bug can be pretty evil if it moves up to 2.5. I am willing to help/test if any GT2 developer that is more experienced than i am contacts me. Skype: alfonx or   krueger et wikisquare.de
