DMN runtime not using the kiecontainer root classloader to load classes ----------------------------------------------------------------------- Key: DROOLS-2441 URL: https://issues.jboss.org/browse/DROOLS-2441 Project: Drools Issue Type: Bug Components: dmn engine Affects Versions: 7.6.0.Final Reporter: Edson Tirelli Assignee: Matteo Mortari Priority: Blocker Fix For: 7.8.0.Final Attachments: Standard Deviation.dmn, StandardDeviation.java The FunctionDefNode is not using the kie container root classloader to load classes. I even added a comment for that, just a shame comments are not executable: https://github.com/kiegroup/drools/blob/master/kie-dmn/kie-dmn-feel/src/m... {code:title=FunctionDefNode.java} // might need to explicitly use a classloader here Class<?> clazz = Class.forName( clazzName ); {code} To reproduce the problem, create a java class with a static method, add it to the kjar, create a DMN model that invokes that model, and try to execute.
