QGIS-45226 reported a Stack Overflow error during KdTree query. PR GEOS-481 fixed this in GEOS by changing the recursive query code to use an explicit stack.
This PR implements the same fix for JTS, replacing
KdTreequery recursion with the use of an explicit stack. It also contains refactoring to clarify the query code and the semantics of KdTree nodes.Signed-off-by: Martin Davis mtnclimb@gmail.com
