Hi,
I migrated some solver code that I had working on 5.0M4 to the 5.1.0
implementation. I'm now seeing the following while running the solver:
java.lang.NullPointerException
at org.drools.solver.core.score.DefaultSimpleScore.compareTo
(DefaultSimpleScore.java:73)
at org.drools.solver.core.score.DefaultSimpleScore.compareTo
(DefaultSimpleScore.java:13)
at
org.drools.solver.core.localsearch.bestsolution.BestSolutionRecaller.stepTaken
(BestSolutionRecaller.java:56)
at
org.drools.solver.core.localsearch.DefaultLocalSearchSolver.stepTaken
(DefaultLocalSearchSolver.java:171)
at
org.drools.solver.core.localsearch.DefaultLocalSearchSolver.solveImplementation
(DefaultLocalSearchSolver.java:121)
at org.drools.solver.core.AbstractSolver.solve(AbstractSolver.java:41)
I ran my test with a debugger attached, and this call is returning a
Null:
Score bestScore = localSearchSolverScope.getBestScore();
<org.drools.solver.core.localsearch.bestsolution.BestSolutionRecaller:
55>
The BestSolution is not null although the best score is.
Should I file an issue on this in JIRA? Or perhaps this reflects some
change to the old code that I didn't migrate properly?
best wishes,
Andrew
