[rules-users] Sharing packages between rule bases?

[Ingomar Otter]

Hello @all.

We are generating quite some rules and we have handcrafted rules.
We'd like to combine both into RuleBases that we use for a limited time.
So far we have parsed the "static packages" and merged these into  
RuleBases we create. We hang on to the "static" packages to avoid  
unnnecessary parsing of these.

This results in a n:m relation between packages and rulebases.
For example:
* Rulebase1 contains Package:Pstatic and Package:P1
* Rulebase2 contains Package:Pstatic and Package:P2
etc..
Is this supported/permitted? Any idea how I can achieve "shared  
packages between rule bases"?

* What we see is a memory leak,. It seems that the generated Rulebases  
(and their classes ) are never unloaded. We are still investigating.

* I included a specific code to remove the packages from the  
rulebases, once we no longer need them.  I use  RuleBase.removePackage  
for this.
To my surprise the "removePackage" method not only removes the package  
from the RuleBase, it also purges the package. :-(

So I do a
myRuleBase.addPackage(myLovelyPackge) followed by
myRuleBase.removePackage(myLovelyPackage.getName()). This leaves  
myLovelyPackge _empty_. Not what I expected.
