Doesn't seem to be. This is the cut from line 3245 to 3262:

      for (j=0; j<TupleDimension; j++) {
        valuesJ = values[j];
        new_valuesJ = new_values[j];
        for (i=0; i<length; i++) {
          float v = Float.NaN;
          int len = indices[i] == null ? 0 : indices[i].length;
          if (len > 0) {
            v = valuesJ[indices[i][0]] * coefs[i][0];
            for (k=1; k<len; k++) {
              v += valuesJ[indices[i][k]] * coefs[i][k];
            }
            new_valuesJ[wedge[i]] = v;
          }
          else { // values outside grid
            new_valuesJ[wedge[i]] = Double.NaN;
          }
        }
      }

Yeah...I can't figure this one out too.

OK...the result is:
f: FunctionType (Real): (time) -> (MinTemp, MaxTemp, WindDirection)
predictedSet: Set(time)
f: FunctionType (Real): (time) -> (MinTemp, MaxTemp, WindDirection)
predictedSet: Set(time)
f: FunctionType (Real): (time) -> (MinTemp, MaxTemp, WindDirection)
predictedSet: Set(time)

I've never really used jdb before but I did catch the exception and typed
the following:
print values.length produces: "values.length" is not a valid local or
class name.

print TupleDimension produces: "TupleDimension" is not a valid local or
class name.
