Geoffrey De Smet commented on JBRULES-3413:
-------------------------------------------
Would you rather get a partially initialized solution?
Note that an initialized solution is not possible, as the time given is less then the
construction heuristic needs.
Note that construction heuristics will be made configurable so they can run faster (for a
score cost).
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.
