Cedric Le Roux updated STORM-3043:
----------------------------------
    Description: 
When using a SimpleRecordTranslator with a user-defined translator Func, a NullPointerException will be thrown if Func.apply() returns null. A null List object is a valid return value from apply() if the ConsumerRecord is invalid.

SimpleRecordTranslator does not check for a null result before attempting to call the addAll method of the List.
