This failure is caused by the changed that is introduced in googleapis/gax-java@cf1bce8

Spanner sets an ExecutorProvider on the TransportChannelProvider. Previously, this meant that an executor would be requested for each channel that was created by the TransportChannelProvider. The setExecutorProvider has now been deprecated and its implementation has been changed to get one Executor to use for all channels, instead of requesting one Executor for each channel. That again means that there are now a lot less threads available for the transport channels than before. I wonder whether that was an intentional part of the change, or more of a side-effect of the change.

I think that we need to add some code changes when upgrading to this latest version to mitigate for this. Otherwise the entire Spanner library will only have 4 threads available for all transport channels for both all the data clients as well as the admin clients.
