Log:
Improved: Fixing defects reported by FindBugs.
(OFBIZ-9451)

Use a StringBuilder to append a certain amount of '*'s to origMaskedNumber.
When using concatenation inside the loop, the String is converted to a new
StringBuilder, appended to, and then converted back to a String anyway.
Therefore the performance is improved by avoiding many StringBuilder
initializations.

ReturnHeaderResp in RefundGcPurchase() is unnecessarily checked for null value.
