Agreed, after a while the code becomes a maze of ifs and special case

Yup, that would work for me. I have to prepare a custom gdal build 
anyways since java bindings do not seem to be included in normal

Well, if special cases are needed just for shapefiles, I just need
to add a little modification. Will try that one, I prefer to publish
real geometry types if possible, and possibly stay with the non 
multi-ones since people are sometimes surprised by them.

Thanks for the insights :-)
