Build failure on master (flaky test?)

[Oberon00]

The failure is:

Picked up _JAVA_OPTIONS: -Xmx1g

io.opentelemetry.exporters.otlp.OtlpGrpcMetricExporterTest > testExport_MultipleMetrics FAILED
    expected: SUCCESS
    but was : FAILED_RETRYABLE
        at io.opentelemetry.exporters.otlp.OtlpGrpcMetricExporterTest.testExport_MultipleMetrics(OtlpGrpcMetricExporterTest.java:93)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':opentelemetry-exporters-otlp:test'.
> There were failing tests. See the report at: file:///home/circleci/project/exporters/otlp/build/reports/tests/test/index.html

Since we seem not to store the test results, I guess that's all we have.

The latest merged PR was #1068 but it seems unrelated.

As the error said that was a "FAILED_RETRYABLE" error :)) I think it was only a transitive failure and you can say it is flaky but I think that it does not happen often. You can maybe run the test 1000 times and see if it fail with a significant rate.

Closing due to lack of activity. @Oberon00 please re-open if you think this was not a transitive failure, as Bogdan commented.
