Here is a test xml: http://www.giovanniallegri.it/share/TestUnionMultiPolygon.xml It's big, but I will reduce it nex time :)
Notes: 1 - this multipolygon comes from an st_collect on 95 rows in a postgis table. The test on it fails with Topology Expection found non-noded intersection, because the MP is invalid. I've tested it on jts from trunk. 2 - I've run a cascadedunion.union operation on a List of the same geometries (picked with Geotools directly from the DB). It works fine. In this test I've used jts 1.10 shipped with Geotools. I will try it agains the trunk version as soon as possible.
