Switching off alpha node sharing changes rule behaviour ------------------------------------------------------- Key: JBRULES-859 URL: http://jira.jboss.com/jira/browse/JBRULES-859 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Components: Reteoo Affects Versions: 4.0.0.MR2 Environment: Windows XP SP2, Intel x86 Pentium 4 3.0MHz, 1Gb RAM Reporter: Shahad Ahmed Assigned To: Mark Proctor In release 4.0MR2, switching off alpha node sharing appears to change the results produced by a set of rules. I'll illustrate the behaviour with the two rules "First" and Second" defined below. Both rules work with a class Customer, which is a simple object with an attribute age. rule "First" salience 10 when c: Customer(age <= 10) then System.out.println("First - Customer age less than 10"); end rule "Second" salience 5 when c: Customer(age <= 10) then System.out.println("Second - Customer age less than 10"); end For the default case where alpha node sharing is on, I assert a customer with age 5 and fireAllRules to get the following (hopefully, correct) output: First - Customer age less than 10 Second - Customer age less than 10 However, if I call setShareAlphaNodes(false) in RuleBaseConfiguration to turn off alpha node sharing I get the following output: First - Customer age less than 10 Alpha node sharing is an optimization and switching it on or off should give the same output for a set of rules. I've tried switching off alpha node sharing both directly via the API method, and using the system property option, but the behaviour is the same in both cases.
