-------------------------------------
Summary: CollectionInputFormat is not able to handle Enums
Key: FLINK-1251
URL: https://issues.apache.org/jira/browse/FLINK-1251
Project: Flink
Issue Type: Bug
Reporter: Robert Metzger
It seems that the CollectionInputFormat is not able to handle POJOs containing enums properly.
{code}
public enum Category {
CAT_A, CAT_B;
}
public static class PojoWithDateAndEnum {
public String group;
public Date date;
public Category cat;
}
{code}
leads to
{code}
