I suspect this may be caused by a known bug in the Unary union. This
was identified in this thread on the JTS list:
http://sourceforge.net/mailarchive/forum.php?thread_name=4C0FB4A5.2010304%40refractions.net&forum_name=jts-topo-suite-user
I fixed this in JTS, in the soon-to-be-release

Heya,
The particular error I had in front of me isn't fixed by ST_Union(the_geom,
the_geom), but it is fixed by ST_Union(the_geom, ST_SetSRID('LINESTRING EMPTY',

Rev 110
Modification was to switch to using SnapIfNeededOverlayOp
private Geometry unionNoOpt(Geometry g0)
{
Geometry empty = geomFact.createPoint((Coordinate) null);
return SnapIfNeededOverlayOp.overlayOp(g0, empty, OverlayOp.UNION);
}

Ok, reviewed... UnaryUnionOp is still unported to GEOS,
all the rest is up to date.
If anyone is willing to sponsor the port I'm available.
