Andrea,

Thank you for your patience, but while exporting my data to send you an 
example, I noticed something wrong with the MultiPolygons with more than 
one polygon.

Just to explain what happened:

Here in TECGRAF we are developing some cool stuff for on top of Geotools 
and we have some applications that uses Terralib model.
The Terralib is INPE´s ( The Brazilian Institue for Spatial Research ) 
GIS library that is entirelly writen in C++. So my features are being 
translated through  JNI code to JTS geometries.
I´ve found that part of the translation code where mixing some C++ 
references, so the final JTS MultiPolygons where with valid sizes but 
some really crazy coordinates.

Now everything is working just fine.

Thank you again for your help and attention
