##### SUMMARY
<!-- Explain the problem/feature briefly -->
When using the API to create affinity groups, it usually works. On rare
instances, a race condition causes a NullPointerException.

For new features, show how the feature would be used.

<!-- Paste example playbooks or commands between quotes below -->

Use the API to create an affinity group. This may take many tries to
reproduce the issue.

<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
The affinity group should be created.
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
There is sometimes a NullPointerException.
See the attached log. It shows that an async job is created and runs. The
output from the async job includes the message `Update db status for
job-131043`, which indicates that the transaction has started which will set
the removed date for the async job. Then when
ApiServer.getBaseAsyncCreateResponse() looks for the job on line 662, it gets a
null value. This causes the NPE to happen on line 663.
