Edson,
NQueens now works (thanks),
but Examination [1] and SmartTravelingTournament still fail.
To run Examination, just create a java application config with these
settings:

org.drools.planner.examples.examination.app.ExaminationBenchmarkApp
VM parameters: -Xms256m -Xmx512m -server

Geoffrey,
All planner tests are green now (revision #32010).
Thanks,

Hey Geoffrey,
The fixes for accumulate are already there. It is no longer
cloning the tuple memory and whenever possible, it uses indexing
instead of full iteration.
Working on the NPE now.

Edson,

Yes, it's no longer there, thanks :)
Examination now suffers from the same NPE as the NQueens smoke test.
On one PAS testdata I actually had 5%, but on another PAS
testdata only 1%.
I believe the cloning in accumulates fix will allow me to do the
score
calculation as it should be done (one rule instead of two rules)
and also further help performance.
I 'll run some experiments in that direction as soon as you give
me the
sign that cloning in accumulates has been fixed.
With kind regards,
Geoffrey De Smet
