see simplePingPong.Boot, with arguments: -node main -pylon local:mainPylon use-thread
some named nodes fail to instantiate their messaging shard (with no error displayed) and this leads to a null pointer exception (see deployment.BootExample version2).

Could be solved after commit 63ffdd4a5e967349ab41e7269a263cccbf209a3a but could also be a race condition somewhere.

Will not trey to avoid the exception (e.g. by checking if messagingShard is null in the idea that it may reappear.

Exception appears again when multiple pylons, not all offering messaging, exist.
