FP: Unsupported method call (2)

[ben-manes]

The Map.put() is unsupported.
This code calls Map.put(). However analysis found that this method as well as 
and its overrides (if applicable) unconditionally throw UnsupportedOperationException,
so it's likely that this call will fail.

This makes little sense to me as it is calling into a HashMap. It must be observing that AbstractMap#put() throws an UOE but the subclass does not.

Map<K, V> result = new HashMap<>(loaded.size());
loaded.forEach((key, value) -> {
  if ((key == null) || (value == null)) {
    nullBulkLoad.set(true);
  } else {
    result.put(key, value);
  }
});

Probably the same as #25 but calling out separately as easier to isolate as a subclass confusion.
