---------------------------------
Summary: 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
{{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}
