    endless sdo_geom.sdo_concavehull

    892079
      Calculating concave hulls over Multipoint geometries doesn't come to an end in some cases.
      For instance the following query runs endlessly:

      select x,y
      from table(sdo_util.getvertices(sdo_geom.sdo_concavehull(
      sdo_geometry(2005,8307, null,
      sdo_elem_info_array(1,1,6),
      sdo_ordinate_array(16.245563347578532,47.81313605484119,
      16.24572,47.81376999,
      16.24572,47.81376999,
      16.245966237709244,47.81439090641379,
      16.24572,47.81376999,
      16.24506984,47.81383002)
      ), 0.00050000000000000001)));

      Is there a known bug?
