RFR JDK-8239264: Clearup the legacy ObjectIdentifier constructor from int array

[Xuelei Fan]

Hi,

Could I get the following update reviewed?
    http://cr.openjdk.java.net/~xuelei/8239264/webrev.00/

For historic reason, the JDK internal ObjectIdentifier instances are 
used to constructed with int arrays (ObjectIdentifier(int[])).  It is 
not a performance and user friendly constructor.  Removing this 
constructor could have a more clear coding style, and better 
performance, by using alternative constructors.

Thanks,
Xuelei
