> The following properties can be observed in many high-frequency test
> instabilities. They are likely sharing a common root cause.
> * Use the Testcontainers framework
> * Fail due to no outputs in long time
> * A stack similar to the following can be find in the thread dump.
> ** Thread is RUNNABLE
> ** Testcontainers DockerClient is being created:
> {{org.testcontainers.DockerClientFactory.client(DockerClientFactory.java:205)}}
> ** Seems to be downloading something via okhttp
