I have checked locally. Problem with this test is coming from `.report()`
invocations race condition
(https://github.com/apache/flink/blob/c73d3ef375911235da9c55973351887735a66185/flink-metrics/flink-metrics-otel/src/test/java/org/apache/flink/metrics/otel/OpenTelemetryMetricReporterITCase.java#L82-L89).
It can happen that first report (with 2 metrics) is logged in the output after
second report (with 5 metrics). Because test utils only uses last report line
for
validation(https://github.com/apache/flink/blob/c73d3ef375911235da9c55973351887735a66185/flink-metrics/flink-metrics-otel/src/test/java/org/apache/flink/metrics/otel/OpenTelemetryTestBase.java#L87),
it "misses" correct report. I will have a look into how best fix it
