IIRC, there were some rather positive statements during the evoluion
of 5.x that a session is thread-safe.

I can see a few independent issues here.
Drools 5.x was not designed to be thread-safe in general: there are some
known
critical races that may arise when multiple threads are inserting
facts in parallel. Many have been patched in 5.6, but the real
solution to the problem will be introduced in the 6.x series.
