Review comment:
We could perhaps also test here that the async details are captured too.
I'll add a small commit, feel free to revert or amend.

Review comment:
Not directly related to the pull request changes here but I wonder if at
https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.9.0/solr/test-framework/src/java/org/apache/solr/SolrTestCaseJ4.java#L433
the info logging might be `if (retries > 0)` qualified i.e. the "Done waiting"
is only applicable if there was a "Waiting for all" to start with.
Or turning the `break` into a `return` at
https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.9.0/solr/test-framework/src/java/org/apache/solr/SolrTestCaseJ4.java#L413
would have the same effect (assuming there's no additional track call
happening after the break and before the clear at line 435).

Review comment:
Hmm, yes, the tests help to demonstrate what is happening. But
explaining it in a comment, well, that is trickier and so yes
`grandParentSubmitter` is concise and comments as well might just add confusion.
