---------------------------------------------------------------
[~tirelli] Thanks 4 all the indications. With that in mind, I changed my project to use no physical kJars but still, I would get the same error as I mentioned, and found 2 others more. I think I am doing all right now. Basically all is related to the SingleAccumulate class:
-org.drools.core.rule.SingleAccumulate.accumulate(SingleAccumulate.java:106)
-org.drools.core.rule.SingleAccumulate.accumulate(SingleAccumulate.java:124)
-org.drools.core.rule.SingleAccumulate.accumulate(SingleAccumulate.java:88)
I created a small maven project and I was able to replicate the problems both using physical kJars and in-memory kJars. I'm attaching it to the issue so you can take a look at it.
Thanks.

> I need to add and remove rules in runtime, without losing facts.
> I'm achieving this by manipulating a kJar on my .m2 folder by adding and removing rules.
> The scanner is attached and the scanNow() method is invoked whenever a change occurs.
> But whenever I load a rule back (say on rule YYY), I get errors on (XXX), seems like it has to do with accumulates and can occur on various rules, something like:
