Avoid ambiguous overload on JDK 9

The addition of this method in `CharBuffer`

   CharBuffer position(int newPosition)

renders an ambiguity in:

```
scala> (b: java.nio.CharBuffer) => b.position
<console>:12: error: ambiguous reference to overloaded definition,
both method position in class CharBuffer of type (x$1: Int)java.nio.CharBuffer
and  method position in class Buffer of type ()Int
match expected type ?
       (b: java.nio.CharBuffer) => b.position
```

Manually applying the empty params avoids this.
