CompletionSuggestion.Entry.Option.getPayloadAsMap() throws NPE if no payload is indexed

Elastic Stack Elasticsearch

Hi,

some of my documents don´t have a payload but some do. If I use following,
I always get a NPE:

        ...
        Iterator<? extends Option> iterator =

response.getSuggest().iterator().next().getEntries().get(0).iterator();
while (iterator.hasNext()) {

            CompletionSuggestion.Entry.Option completionOption =

(CompletionSuggestion.Entry.Option)iterator.next();
System.out.println("###: " +
completionOption.getPayloadAsMap()); // in ES v1.1.1
getPayloadAsMap() results in NPE
...

Stacktrace:

java.lang.NullPointerException

org.elasticsearch.common.xcontent.XContentFactory.xContent(XContentFactory.java:117)
