> Validate lower bound in MathUtils.checkedDownCast
> -------------------------------------------------
>
> Key: FLINK-4594
> URL: https://issues.apache.org/jira/browse/FLINK-4594
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Trivial
> Fix For: 1.2.0
>
>
> {{MathUtils.checkedDownCast}} only compares against the upper bound
> {{Integer.MAX_VALUE}}, which has worked with current usage.
> Rather than adding a second comparison we can replace
> {noformat}
> if (value > Integer.MAX_VALUE) {
> {noformat}
> with a cast and check
> {noformat}
> if ((int)value != value) { ...
> {noformat}
