appearing with some of the tests that Tyson wrote to exercise cosmosdb sdk.

com.azure:azure-cosmos:4.0.1 with jdk 1.8 and jdk 11.

Tyson is trying to narrow down a test case, but it happens intermittently, about 50% of the test runs.

@tysonnorris do you have any more details/test/repo-steps you can provide? ( I added “need-author-feedback”).

Thanks @kushagraThapar - I will try to port our existing usage of AsyncDocumentClient to CosmosAsyncClient
