Geoffrey De Smet resolved JBRULES-3413.
---------------------------------------
Fix Version/s: 5.5.0.Beta1
Resolution: Done
Fixed. Instead of an NPE, it does generate a report now, for example:
{code}
Solver medium01 long02 medium_hint01 medium_hint02 Average Ranking
tabuSearch-moveTabu 0hard/-373soft failed 0hard/-171soft 0hard/-542soft 0hard/-362soft 0
{code}
Notice the "failed" benchmark.
In the log, you see this until JBRULES-3462 is fixed:
{code}

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
Fix For: 5.5.0.Beta1
Running a benchamrk on a slow machine throws a NPE because there is no best solution
found yet.
