Description

  // to save and report costs to JMX
  private Double curOverallCost = 0d;
  private Double[] tempFunctionCosts;
  private Double[] curFunctionCosts;

It seems we never do null check on these field or the elements, so I do not see any reason we should use Double here. Just use double instead.
