Error when using option "memoryPreloadingEnabled" and use SLD filter
--------------------------------------------------------------------
Key: GEOT-1256
URL: http://jira.codehaus.org/browse/GEOT-1256
Project: GeoTools
Issue Type: Bug
Affects Versions: 2.3.0
Environment: Windows
Reporter: Miguel Angel Vega Pabon
Priority: Critical
Fix For: 2.4.0
Attachments: BUGs.zip
I'm developing some libraries, that make easier the handle of geotools, but
i've got the next error:
java.lang.ClassCastException: org.geotools.filter.Filter$1 cannot be cast to

This happens when i'm using Postgis connection and StreamingRenderer with the
property "memoryPreloadingEnabled" as true. This bug doesn't seems to occurs
when i use shapefiles.
The code of the program is the next:
