After having a look in the EAP 7.1 jobs, this was the case there as well, so it's not
new. The pattern is similar, which is the reason it fell through our checkers, but there
are no related NoSuchEjb exceptions here.
These occur fairly often - that is hundreds of times for 2000 clients each making
invocations every 4 seconds.
