RFR: 8282316: Operation before String case conversion [v3]

[Xue-Lei Andrew Fan]

> In the SignatureUtil implementation, the checkName() requires case-insensitive input for "OID".  However, the method is called before the case conversion, for example: 
> 
>             sigName = checkName(sigName).toUpperCase(Locale.ENGLISH); 
> 
> This update also clean up redundant calls to the checkName() method.
