[ https://issues.redhat.com/browse/DROOLS-6030?page=com.atlassian.jira.plug... ] Mario Fusco commented on DROOLS-6030: ------------------------------------- [~gabriolo] Thanks for quick reply. I'm giving a look into this. Correct me if I'm wrong but 1) doesn't seem related with this issue because there you're using the addPackage method of the KnowledgeBuilder, not the KieBase one and that one is perfectly fine. There you're adding the packages to be built to the builder and then a new KieBase will be created from there. What [~lucamolteni]  pointed out to be more problematic is the usage of the addPackage method directly on the KieBase that you have in 2). By doing so you're no longer adding packages to a builder and then obtaining the KieBase with the required packages from the builder, but you're adding packages (here I'm generally speaking about "packages" but of course they're a different thing at this stage) directly to an already existing KieBase. I don't know how feasible it is in your context (and if I remember correctly we already discussed this) but ideally we should have in 2) something similar to what we have in 1), i.e. putting together the packages to be included in the KieBase at building time. -- This message was sent by Atlassian Jira (v8.13.1#813001)
