[FLINK-6909] [types] Fix error message in CsvReader for wrong type class
----
> Flink should support Lombok POJO
> --------------------------------
>
> Key: FLINK-6909
> URL: https://issues.apache.org/jira/browse/FLINK-6909
> Project: Flink
> Issue Type: Wish
> Components: Type Serialization System
> Reporter: Md Kamaruzzaman
> Assignee: Timo Walther
> Priority: Minor
>
> Project lombok helps greatly to reduce boilerplate Java Code.
> It seems that Flink does not accept a lombok POJO as a valid pojo.
> e.g. Here is a POJO defined with lombok:
> @Getter
> @Setter
> @NoArgsConstructor
> public class SimplePojo
> Using this Pojo class to read from CSV file throws this exception:
> Exception in thread "main" java.lang.ClassCastException:
> org.apache.flink.api.java.typeutils.GenericTypeInfo cannot be cast to
> org.apache.flink.api.java.typeutils.PojoTypeInfo
> It would be great if flink supports lombok POJO.
