Incremental update leaks globals -------------------------------- Key: DROOLS-752 URL: https://issues.jboss.org/browse/DROOLS-752 Project: Drools Issue Type: Feature Request Components: core engine Affects Versions: 6.2.0.Final Environment: Mac OS X 10.10.2, Oracle Hotspot 1.7.0_71 Reporter: Duncan Doyle Assignee: Mario Fusco Fix For: 6.3.0.Beta1 The incremental update feature of Drools allows me to incrementally update not only the KieBase, but also the KieSession. I have a use-case where my updated rules have different globals defined (different classes) than the original rules, with different names. When I set a global on a KieSession, Drools explicitly checks whether that global is defined in the KieBase, and if not, it will throw an error. However, when I incrementally update the KieBase, and a global is removed from the rulebase, that global is not removed from the MapGlobalResolver map, potentially causing issues (e.g. memory leaks). When a session is incrementally updated, and globals are no longer defined in the new rule-base, they should be removed from the MapGlobalResolver.
