> AbstractCell#toString is broken when calling on some cells in multi-cell collections.
> With the following types are unmarshallable: [date, duration, smallint, time, tinyint].
> The test to discover the unmarshallable types is
> {code:java}
> @Test
> public void testUnmarshallableInMulticellCollection()
> {
>     List<CQL3Type.Native> unmarshallableTypes = new ArrayList<>();
>     for (CQL3Type.Native nativeType : CQL3Type.Native.values())
>     {
>         ColumnMetadata c = fakeColumn("c", MapType.getInstance(Int32Type.instance, nativeType.getType(), true));
>         BufferCell cell = BufferCell.tombstone(c, 0, 4, CellPath.create(ByteBufferUtil.bytes(4)));
>         try
>         {
>             cell.toString();
>         }
>         catch (MarshalException m)
>         {
>             unmarshallableTypes.add(nativeType);
>         }
>     }
>     System.out.println("Unmarshallable types: " + unmarshallableTypes);
> }
> {code}
> At the first sight, the error is caused by trying to deserialize the values of the tombstone cells. The values are empty, hence the failure.
