-----------------------------------------------------------------------
Looks like the measured time interval does not entirely cover the timeout. The
tests in java 11 were sometime falling a few ms short. Adding a fudge factor
should help.
edit: On second thought, it is probably better to just refresh the timeout,
like in testIdleDisconnectProlonged.
