[ https://issues.redhat.com/browse/DROOLS-6030?page=com.atlassian.jira.plug... ] Gabriele Cardosi commented on DROOLS-6030: ------------------------------------------ [~mario.fusco1] As per description, the invocation itself is present in two classes, with slightly different reasons: 1) PMMLLoaderService.loadPMMLRuleMappers is called (mainly) starting from Kogito, where the org.drools.model.Model are instantiated from (compiled) classes, a new KnowledgeBuilderImpl is built out of such models, and then the newly built packages are added to the parameter KnowledgeBuilderImpl (see [method|https://github.com/kiegroup/drools/blob/706f219d1877152d885a1acbef...]) 2) inside PMMLRuntimeFactoryInternal, a new "clean" KieBase is created out of the provided one, and populated only with packages relevant for the evaluated model (see [here|https://github.com/kiegroup/drools/blob/706f219d1877152d885a1acbef3d...] and [here|https://github.com/kiegroup/drools/blob/706f219d1877152d885a1acbef3d...]) 2) : replace it with the preferred one and do thorough tests could take one or two days. But the real issue is: what is the preferred one ? As far as I know, the use case by itself has never implemented/requested before, and I have not the required knowledge of drools-core to estimate how much time it could need to create a "nice" implementation. -- This message was sent by Atlassian Jira (v8.13.1#813001)
