Thanks for the post Thomas. Actually, I wanted to load and unload KBs WHILE I
am running the rules. That was not a problem at all, and it is not a problem
with many other KBs.
I was inspired by your post (so thank you very much) and started looking to
maybe externalizing the removal from the rul

Any help is appreciated. I am stuck on this. I stripped everything down to
two simple drls, and one of them loads the other as a new KP, and then tries
to unload it.
Any ideas why the removeKnowledgePackage could possibly throw a
NullPointerException in M1?? This is really hurting us as we are go
OK. So, I did an isolated test, and only tested two KP including this bad
one. Both packages have their complete set of rules. But now, the other
package is able to remove this faulty one.
So, it is when I had my complete set of KPs (about 10 of them) all active,
and then attempted to remove this
Again, there is probably no deadlock because if you look at the bold part of
the stack trace I posted in the first post (and again below), it seems like
it is throwing a NullPointerException and it is somehow killing the thread
without returning back to my application (from Drools). Here are my

Thanks Greg. I just did what you suggested, and although I was able to
regenerate the exact same scenario, I clicked on Detect Deadlock from
JConsole and it said: No deadlock detected.

I found out one more thing, this call above consistently happens with that
rule and the package it is unloading. I checked another rule that unloads
another package and it works consistently fine.
What could be the problem? I am assuming that if there are threads launched
by Drools to execute rul
I am trying to unload a KnowledgePackage that is already loaded in my
KnowledgeBase. The call:
this.knowledgeBase.removeKnowledgePackage(knowledgePackage.getName());
hangs (never returns). I had a similar problem with adding a
KnowledgePackage to a KnowledgeBase and someone on here suggested tha
