Revision 23

The old code must have been a mistake, because it would have led to a NullPointerException. Eclipse showed me these...

Old:
    if ( sfc != null || sfc.getFeatureCollection().size() > 0 ) {
      FeatureCollection fc = sfc.getFeatureCollection();

New:
    if ( sfc != null && sfc.getFeatureCollection().size() > 0 ) {
      FeatureCollection fc = sfc.getFeatureCollection();
