Fix for 5015163, and my first webrev

[Xueming Shen]

public String join(Object first, Object... elements) {
     if (elements.length==0)
         return String.valueOf(first);
     return new StringBuilder().join(this, first, elements).toString();
}

It does not look right to simply return String.valueOf(first); when 
elements size is 0, where is "this"?

No, I'm not endorsing the APIs provided, at least for now:-) there is 
room to debate what would be
the best choice(APIs) to support the "joint", if we decided to add one.
