Review comment:
This constructor is `public` (can be used directly, skipping
`ServiceProviderBuilder`), and now it accepts both `ThreadFactory` and
`CloseableExecutorService`, which can be confusing.
I suggest to make this constructor package-private and add 2 `public`
constructors: one that accepts all arguments as this one but only
`ThreadFactory` (no `CloseableExecutorService`) and second that accepts all
arguments as this one but only `CloseableExecutorService` (no `ThreadFactory`).
Both will delegate to this constructor (with `null` as the missing argument).
