There are 2 commits in this PR - one is general clean up and additional logging and the second one is the actual fix where we `close()` the server side `Executor` before asserting a counter state in the main thread. Closing the server side `Executor` waits till the HttpHandler instances return from their handle() method and thus prevents these intermittent test failures.
