<div dir="ltr">Exactly correct. I also tried to tell that the problem was originated from org.postgis.GeometryCollection constructor. So I posted to here to understand why constructor was behaving like this. This constructor is in postgis-jdbc.jar . Anyone knowing about this problem on the org.postgis.GeometryCollection constructor?</div>
