Review Comment:
In any case, something like this is what you have in mind?
```
for (Map.Entry<?, ?> e : map.entrySet())
{
Object key = e.getKey();
ByteBuffer previousValue = bbs.put(objectToBytes(key),
objectToBytes(e.getValue()));
if (previousValue != null)
throw new IllegalStateException("Key " + key + " already maps to
value " + previousValue);
}
```
