IT Failure(google-cloud-compute): ITPaginationTest.testPaginationIterating zone not found
Failures observed in GraalVM nightly build and presubmit. This error is happening often (in a number of presubmits and re-triggers), but not consistently:
Problematic test - com.google.cloud.compute.v1.integration.ITPaginationTest.testPaginationIterating
Failures (1):

This could be a similar issue with interfering compute resources from integration tests as observed/addressed in https://github.com/googleapis/google-cloud-java/pull/8260.
Update - seems like this is a previously observed flake coming back: https://github.com/googleapis/java-compute/issues/683, https://github.com/googleapis/java-compute/pull/682#issuecomment-1108555217 look relevant.
An initial investigation from locally reproducing this error w/ Terraform:
gcloud compute zones list returns 119 zones, which also consistent with the response.iterateAll() size from testList().
In testPaginationIterating(), iterating over zones sometimes gets stuck at around this point:
...
Zone: europe-west9-b
Zone: europe-west9-a
Zone: me-central1-b
Zone: me-central1-c
response.IterateAll() size: 46
And sometimes able to get a full list including us-central1-a (DEFAULT_ZONE):
...
Zone: europe-west9-b
Zone: europe-west9-a
Zone: me-west1-a
Zone: me-west1-c
Zone: me-west1-b
...
Zone: us-central1-a
...
The nightly builds are back to green, and I am no longer able to reproduce this error 🤔. Leaving this issue open to track and revisit if it resurfaces again.
Closing this issue now. It's been ~3 months since this last flaked. We can re-open if this test flakes again.
