   Type org.jfree.chart.axis.ModuloAxis of variable a1 does not match with type org.jfree.data.time.TimeTableXYDataset of variable d1

   Preondition Violations
   Unmatched statement a2=(ModuloAxis)in.readObject(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
