-----------------------------------
Summary: Fix "mim" typo in AggregatedMetric.toString() in operator
and autoscaler-standalone modules
Key: FLINK-39691
URL: https://issues.apache.org/jira/browse/FLINK-39691
Project: Flink
Issue Type: Bug
Components: Kubernetes Operator
Reporter: Pavel Zeger
## Where
Two copies of `AggregatedMetric` still contain the typo:
-
`flink-kubernetes-operator/src/main/java/org/apache/flink/runtime/rest/messages/job/metrics/AggregatedMetric.java`
line 130
-
`flink-autoscaler-standalone/src/main/java/org/apache/flink/runtime/rest/messages/job/metrics/AggregatedMetric.java`
line 130
Both contain:
```java
+ ", mim='"
+ min
```
## Why this is a bug
The third copy of the same file
(`flink-autoscaler/src/main/java/org/apache/flink/runtime/rest/messages/job/metrics/AggregatedMetric.java`)
was already fixed by hotfix commit `e8f1e23` ("Fix typo in AggregatedMetric
string representation", Feb 2026):
```diff
- + ", mim='"
+ + ", min='"
+ min
```
but the maintainer only fixed one of the three places. The other two still
print `mim=` in the value of `toString()`, which:
- Makes log output / debug printing look broken to anyone reading it.
- Causes inconsistency between the three modules — a `toString()` of the
same object differs depending on which copy of the class is on the classpath.
- Wastes time for any future engineer who greps for "mim" trying to
understand whether it's intentional.
## Reproduction
```bash
grep -rn '"mim=' flink-kubernetes-operator/src/main/java
grep -rn '"mim=' flink-autoscaler-standalone/src/main/java
```
Both return the line above.
## Proposed fix
Apply the same one-character fix to both files:
```diff
- + ", mim='"
+ + ", min='"
+ min
```
Plus add a unit test that asserts `toString()` produces the correct field name.
The test covers all three copies and prevents regression.
