NPE during benchmark when no solution found so far -------------------------------------------------- Key: JBRULES-3413 URL: https://issues.jboss.org/browse/JBRULES-3413 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-planner Affects Versions: 5.4.0.Beta2 Reporter: Martin Vecera Assignee: Geoffrey De Smet Running a benchamrk on a slow machine throws a NPE because there is no best solution found yet.
