Hey everyone,
I'm using Drools in a multithreaded environment where multiple KnowledgeBuilder and
StatefulKnowledgeSessions are created parallel. Until now everything runs smooth, but
suddenly I got this error:

Could be a bug.
Do you have a rule containing a pattern
NormalizedNamedEntity( this ... )
or similar? Or a trace showing which rule fires, and what it inserts?
If not, add logging - without this info it's hopeless.

Hey Wolfgang,
I'm generating rules automatically with a genetic algorithm, so I don't know how
the rule looks like.
But the rule creation has constraints which will make each rule to something like this:
when
$[number]:Class(
(Some declarations),
[Optional check for something])
[Optional eval with random conditions to check]
...
then
...
So I'm not using "this" in a rule, never. Also not in the conclusion of the
rule.
Here's a automatically generated rule:
rule "434"
no-loop
when
$0:NormalizedNamedEntity(
ct_0:CoveredText,
cp_0:Concept,
label_0:getConcept().getPrefLabel().value,
areOverlapping($0))
$1:NormalizedNamedEntity(
ct_1:CoveredText,
cp_1:Concept,
label_1:getConcept().getPrefLabel().value,
isLower($1,$0))
$2:NormalizedNamedEntity(
ct_2:CoveredText,
cp_2:Concept,
label_2:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("anatomicpart"))
then
int start = getStart($0,$0,$1,$1,$0,$2);
int ende = getStop($0,$0,$1,$1,$0,$2);
String attribute = label_0+" "+label_0+" "+label_1+"
"+label_1+" "+label_0+" "+label_2;
insert(annotate(aJCas, "de.cloud4health.odm.eprd.itemGroup.operation", 435,
attribute, start, ende, "", attribute));
end
I'll try to reproduce the error and then write out the rule which throws the
exception.
Greetings
Bojan

Please bear in mind that the rule firing when the exception is raised
merely inserts a fact that triggers the evaluation of (most likely)
some other rule, one where the inserted fact could match. So you have
two pointers: the occurrence of one or more NormalizedNamedEntity, and
the occurrence of the inserted fact. Hopefully the latter isn't the
same as the first...
You should be able to exclude all rules that have fired successfully.
