Till Rohrmann updated FLINK-6921:
---------------------------------
Priority: Critical (was: Major)
> EnumValueSerializer cannot properly handle appended enum values
> ---------------------------------------------------------------
>
> Key: FLINK-6921
> URL: https://issues.apache.org/jira/browse/FLINK-6921
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Affects Versions: 1.3.1, 1.4.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Critical
>
> The {{EnumValueSerializer}} fails with an {{ArrayIndexOutOfBoundsException}}
> if we try to ensure compatibility with an {{Enumeration}} which has added a
> field. The problem is that we don't check the array bounds of the array
> containing the enum names in {{ScalaEnumSerializerConfigSnapshot}}.
