Geoffrey De Smet commented on JBRULES-3649:
-------------------------------------------
Regression in 5.5.0.Beta1 from 5.4.0.Final.
How to reproduce:
This bug occurs in a Benchmark with BEST_SOLUTION_CHANGED if it runs a Solver that starts
from an initialized solution (=> no active construction heuristic) and the entire
solver run doesn't improve the score.
How to workaround:
- Disable BEST_SOLUTION_CHANGED
- Or run the Solver longer
Fixed for 5.5.0.Beta2.
