Hi,

I am trying to index a large JSON file in Elasticsearch but, some malformed date variables (containing `'\n'` inside date) is causing exception. I already came across this: [https://www.elastic.co/guide/en/elasticsearch/reference/5.0/dynamic-field-mapping.html#dynamic-field-mapping](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/dynamic-field-mapping.html#dynamic-field-mapping) but I wanted to do this from the Java API. Can you please help?

Thanks in advance.
