RFR: 4247235: (spec str) StringBuffer.insert(int, char[]) specification is inconsistent

[Jim Gish]

Please review 
http://cr.openjdk.java.net/~jgish/Bug4247235-Add-Blanket-Null-Stmt/ 
<http://cr.openjdk.java.net/%7Ejgish/Bug4247235-Add-Blanket-Null-Stmt/>

This minor spec change (which will require CCC approval), adds blanket 
null-handling statements to both StringBuffer and StringBuilder, 
equivalent to the one already in String.

Thanks,
    Jim
