Re: [rules-users] Rules don't execute using MVEL syntax in RHS - Possible Bug
Repeated executions show varying results: sometimes it's OK, sometimes it isn't.
I don't think it's a race condition in your code (although proper
syncing on the map would be the "clean" way to go).
I think that salience doesn't work properly )(6.0.0, OP used 6.0.1.),
if a fact is matched unconditionally by a high salience rule and the
same fact is matched using constraints in rules with lesser priority.
(Wasn't this recognized before as a bug in 6.0.x?)

Hi,
I updated my test code to use your way of creating the Knowledge Base
(using
KieBase) and I have the exact same results. Does anyone have an idea why
this is still failing?
Furthermore, I think the way I was initializing my rules is also supported
by Drools 6, because it's almost copied line by line from the Official
Drools API page:
https://docs.jboss.org/drools/release/6.0.1.Final/kie-api-javadoc/
/
A Typical example to load a rule resource.
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newUrlResource( url ),
ResourceType.DRL );
if ( kbuilder.hasErrors() ) {
System.err.println( builder.getErrors().toString() );
}
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages( builder.getKnowledgePackages() );
StatefulKnowledgeSession ksession =
knowledgeBase.newStatefulKnowledgeSession();
ksession.insert( new Fibonacci( 10 ) );
ksession.fireAllRules();
ksession.dispose();/
Best,
Josep
