Re: [rules-users] Streaming mode

i see that there are some other threads that insert new event and
some
others retract them.
How is the thread model?
Contrary to claims made on this mailing list, StatefulKnowledgeSession is
not thread-safe (this may be due to bugs, but bottomline is: it's not
thread-safe). In order to avoid errors due to multi-threading, don't use
fireUntilHalt(), instead synchronize on the session and only call insert()
and fireAllRules() while synchronized on the session:
synchronized (session) {
entryPoint.insert(event);
session.fireAllRules();
}
