I've spoken to Stuart about this last point. The @SafeVarargs covers
uses of Array.asList and covers the declaration of the asList method
itself. However, it does not cover calls to the constructor inside the
asList method, a constructor which itself is *not* @SafeVarargs.
* @SuppressWarnings("varargs") on the asList method
* @SuppressWarnings("varargs") on new temporary variable for that
purpose (with possible class file size consequences)
* @SafeVarargs on the ArrayList constructor
