Misleading comment in source code for Boolean.toString

The source code for Boolean says:

    /**
     * Returns a new String object representing this Boolean's value.
     */
    public String toString() {
return value ? "true" : "false";
    }

but in fact the String object returned is not "new". The comments for
Object.toString and Character.toString do not promise a "new" object.
I believe the comment for Boolean.toString is in error.
