Thanks in advance. E.
The bug GEOT-4795 still exists as far as I can tell, even though it was posted as fixed in 2011.
I'm sure it's something I've got configured wrong, here's my maven, below.
FYI: very confusing with little documentation related to what version of JTS goes with which version of GeoTools for all the versions of GeoTools (like 10, 11, 12). Can provide time in the saddle to test, document, etc. these issues, let me know.
