Hello Ludji, I just tried running the Quickstart example using GeoTools version 8.0-SNAPSHOT but can't reproduce this error. I guess there is a bug in the MapViewport class which only occurs with some data.
Can you tell me what tutorials you were using please and if the problem happens with any shapefile or only with some. If you are using your own data, please send me a small sample (off list) that provokes the problem.
