[Geotools-gt2-users] TopologyException on EnhancedPrecisionOp union

[Joel M. <jm...@gm...>]

Hi all,
has anyone seen/know how to deal with this exception? I'm guessing it is a
robustness issue, but I thought that this was supposed to be fixed by
version 1.7. If anyone has any ideas they would be most appreciated.
Here's the exception:

*com.vividsolutions.jts.geom.TopologyException: side location conflict [ (
