The bug can be reproduced with several Sudoku samples, e.g., "Medium". You can
[Step] towards the solution, and watch out for "But cell...matches" on standard
output. Many prints are enabled, and it's easy to see from the grid dump that the rule
should not fire in some cases. (Due to this, the data in the model becomes inconsistent.)
Also, execution is not deterministic. Running "Medium" repeatedly with [Solve]
results in different (invalid) final states, with different sets of cells remaining
empty.

The set of rules has been reduced even more. To see the problem, select sample sudoku
"Hard 4++" and klick on [Step]. On standard output:
column elimination due to [3,7]: remove 3 from [2,7]
But cell [3,8]: matches!
But cell [5,8]: matches!
This indicates the firing that should not be. All cells are shown below "=== State of
grid when rule misfires ===".

Wolfgang Laun commented on JBRULES-2873:
----------------------------------------
After setting up an activation event listener for the rule "column elimination"
and with specific cells, I see that the rule fires correctly, saying
column elimination due to [8,2]: remove 5 from [4,2]
This update creates two erroneous activations:
ActivationCreatedEventImpl: column elimination: $i=$i=5, $c=[5,0]: /$c.free=[3, 4, 5, 9],
in org.drools.examples.sudoku.CellSqr@f70ee1 and in column 0, $cx: [2,0]: /$cx.free=[1,
2, 3, 4, 5], in org.drools.examples.sudoku.CellSqr@1bbd583 and in column 0, not: [5,1]:
/not.free=[4, 5, 9], in org.drools.examples.sudoku.CellSqr@f70ee1 and in column 1
ActivationCreatedEventImpl: column elimination: $i=$i=5, $c=[3,0]: /$c.free=[3, 5, 9], in
org.drools.examples.sudoku.CellSqr@f70ee1 and in column 0, $cx: [2,0]: /$cx.free=[1, 2,
3, 4, 5], in org.drools.examples.sudoku.CellSqr@1bbd583 and in column 0, not: [5,1]:
/not.free=[4, 5, 9], in org.drools.examples.sudoku.CellSqr@f70ee1 and in column 1
The second one fires (this is the error):
BeforeActivationFiredEventImpl: column elimination: $i=$i=5, $c=[3,0]: /$c.free=[3, 5,
9], in org.drools.examples.sudoku.CellSqr@f70ee1 and in column 0, $cx: [2,0]:
/$cx.free=[1, 2, 3, 4, 5], in org.drools.examples.sudoku.CellSqr@1bbd583 and in column 0,
not: [5,1]: /not.free=[4, 5, 9], in org.drools.examples.sudoku.CellSqr@f70ee1 and in
column 1
This firing removes the other activation.

Wolfgang Laun commented on JBRULES-2873:
----------------------------------------
I have added rules (with low salience) ending one and two patterns earlier than the full
rule "column elimination" and monitored their activation events. From this, it
can be seen that the CE
not Cell( this != $c, free contains $i, cellSqr == $cs, cellCol != $cc )
is indeed the "guilty" one: the (invalid) activation for the rule ending with
this CE is created at the same time as the (also invalid) one for the full rule.
For the rule ending with
$c: Cell( free contains $i, $cs: cellSqr, $cc: cellCol )
3 and 4 activations for cells $c = [3,0] and [5,0], respectively, are created correctly;
all of them remain active until the end.
