> There are "unsafe" conversions in the Kafka connector.
> CaseInsensitiveStringMap comes in which is then converted the following way:
> {code:java}
> ...
> options.asScala.toMap
> ...
> {code}
> The main problem with this is that such case it looses its case insensitive nature
> (case insensitive map is converting the key to lower case when get/contains called).
