1. fix: use core pool size 1 for maintainer …

   The multiplexed session maintainer used a ScheduledExecutorService
   with a core pool size of zero. This can cause high CPU usage on
   Java 8 due to https://bugs.openjdk.org/browse/JDK-8129861. Also
   on higher versions of Java, it is better to use an executor with
   at least one core thread, instead of letting the executor create
   a new thread every time a task needs to be executed.
