It then proceeds to write out a log message at `DEBUG` level and expects the log message to have been delivered to the handler.  This should all work fine and does work fine except for those intermittent failures.

For a test like this one which deals with log level management of `java.util.logging` infrastructure, in theory, there are chances that some other tests within the same JVM instance might impact the output and can potentially contribute to intermittent failures like this one.

Today is one such occasion - successful login, but it still shows me as logged out and doesn't allow me to do anything. So I decided to directly create this PR instead of first commenting there.

Thanks for looking into this bug. The test was written by me and I have always wondering why it could fail again and again. Your explanation might be the reason so let's give it a try. Approved.
