[jboss-jira] [JBoss JIRA] Updated: (JBRULES-2749) Various rules stop firing when adding more, totally unrelated rules to a knowledge base

Various rules stop firing when adding more, totally unrelated rules to a knowledge base --------------------------------------------------------------------------------------- Key: JBRULES-2749 URL: https://issues.jboss.org/browse/JBRULES-2749 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-compiler (expert), drools-core (expert) Affects Versions: 5.1.1.FINAL Environment: Environment 1: Fedora Core 12 x86_64, Sun JVM 1.6.0_20 64-bit Server VM Environment 2: Windows XP Professional, Service Pack 3, 32 bit; Sun JVM 1.6.0_20 32-bit Server VM Reporter: Ansgar Konermann Assignee: Geoffrey De Smet Fix For: 5.2.0.CR1 Attachments: drools-boundary-tests.git.ZIP A certain rule suddenly stops firing when adding more and more rules to the knowledge base, which (not only?) on first sight have *nothing* to do with the rule in question. We created a few unit tests which show the faulty behaviour. What we observed so far: * when using declared functions plus declared data types, this error occurrs. * sometimes, one can work around this problem by renaming a package. We're not sure if this is a reliable workaround, i. e. works in all situations. * one can work around this problem by not using declared functions. We're not sure if this is a reliable workaround. Find attached a ZIPed git repository containing: * a Maven 2.1+ pom.xml suitable to trigger the unit tests via mvn test * Java source files for a TestNG-based unit test * example drools source files to illustrate the problem (used by the unit tests) Please have a look at java file RuleDoesNotFireIfUsingDeclaredFunctionAndTooManyPackages.java. This should make quite clear what we're expecting of the drools library and where it fails to fulfil these expectations.
