Hello, sorry, I do not remember if/how I resolved the issue.  I currently use
a persisted stateful session (Drools 5.5) retracting the facts I insert with
a rule with high salience and everything works fine.

I did bump into an issue recently where a rule with a bad mvel expression (a
variable in a regex matches that contained an invalid value) was causing an
exception in the bowels of mvel/drools and keeping my rule from firing that
retracts the objects I insert  (so eventually I'd run out of memory).  My
point: make sure you test with a simple / value rule.
