KieContainerImpl.updateResourcesIncrementally throws NullPointerException when a package doesn't exist ------------------------------------------------------------------------------------------------------ Key: DROOLS-511 URL: https://issues.jboss.org/browse/DROOLS-511 Project: Drools Issue Type: Bug Affects Versions: 6.0.0.Final Reporter: Mike Wilson Assignee: Mario Fusco Labels: backport-to-6.0.x Fix For: 6.2.0.CR1 When calling KieContainerImpl.updateToVersion(ReleaseId), we sometimes experience a NullPointerException during a chained set of method calls that try to obtain a package, and then a rule within it. If the package is null, a NullPointerException is thrown, because there is no check in place before that call to get the rule from the package. To prevent this, a null check should be added to the package before trying to get the rule from it.
