Hi, Delete then the .qix index files as well. GDAL and Geotools create those and old index file has similar odd effects with GDAL- and Geotools-based software. http://www.gdal.org/ogr/drv_shapefile.html

When I add features to a shapefile layer that was created by ESRI and save changes, the SBN and SBX optional spatial index files are not updated (when present), This causes problems when viewing in ESRI-based software which assumes that the spatial indexes are up to date with their associated shapefiles. According to Wikipedia, these index files are not supported by any software except ESRI and are "not strictly necessary." My testing seems to confirm that deleting them does no harm. I suggest that we check for the existence of shapefiles with.sbn and .sbx extensions (not to be confused with SHX database index files) and delete them as part of the process of writing or updating a shapefile. This should probably go at the end of com.vividsolutions.jump.io.ShapefileWriter.write.
