-----------------------------------
Hey Timo,
So the rules for defining a POJO according to
[this|https://github.com/apache/flink/blob/master/docs/internal_types_serialization.md]
include this part {quote} All fields in the class (and all superclasses) are
either public or or have a public getter and a setter method that follows the
Java beans naming conventions for getters and setters. {quote}
So that means that it could have private fields. I was thinking we should add
{{field.setAccessible(true)}} in the implementation for {{PojoField}}.
Otherwise something like {{pFieldValue = pField.field.get(myPojo)}} does not
seem to work.
I ran into while I was testing the CSV writer with POJOs with private fields
but public getter/setters.

> It would be great if one could simply write out POJOs in CSV format.

> public class MyPojo {
> String a;
> int b;

> {code}
> # CSV file of org.apache.flink.MyPojo: String a, int b
