I have been seeing a lot of these exceptions lately. I'm using the latest
2.6.4 and this probably didn't happen in 2.4.x that I was using before. I
checked with isValid() method and they are said to be all valid. Therefore,
the original shape is valid. I found that this particular piece of code from
LabelCacheImpl is causing the issue:
PreparedGeometry pg = PreparedGeometryFactory.prepare(geom);
// if(!pg.contains(centroid)) {
// Envelope env = geom.getEnvelopeInternal();
// LineString bisector = geom.getFactory().createLineString(new
Coordinate[] {
// new Coordinate(env.getMinX(), centroid.getY()),
// new Coordinate(env.getMaxX(), centroid.getY()) });
// Geometry intersection = bisector.intersection(geom);
// Envelope widestEnv =
widestGeometry(intersection).getEnvelopeInternal();
// double midX = (widestEnv.getMinX() + widestEnv.getMaxX()) / 2;
// centroid = geom.getFactory().createPoint(new Coordinate(midX,
centroid.getY()));
// }
I have commented out these lines to have a temporary workaround to this
problem.
