Yes, but I just fired up a small project using it and it used 100% of CPU. If you build the attached project you'll see the tests run just fine. (They use fireAllRules.) If you launch from the commandline, ("java -jar target/DroolsBoxes-1.0.jar") which uses fireUntilHalt, the rules fire (and complete) just fine, but it continues to use 100% of a cpu core indefinitely. This is with 5.1.1. If I change the drools version to 5.2.0-SNAPSHOT it compiles but the tests won't run. They all fail with the following exception: java.lang.NoSuchMethodError: org.drools.spi.DeclarationScopeResolver.<init>([Ljava/util/Map;Ljava/util/Stack;)V at org.drools.rule.builder.RuleBuildContext.<init>(RuleBuildContext.java:72) at org.drools.compiler.PackageBuilder.addRule(PackageBuilder.java:1198) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:629) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:278) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:451) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at com.sample.DroolsTest.readKnowledgeBase(DroolsTest.java:75) at com.sample.DroolsTest.go(DroolsTest.java:31) at com.sample.BoxTest.test0(BoxTest.java:21) --- On *Thu, 3/17/11, Edson Tirelli <ed.tirelli(a)gmail.com&gt;* wrote: From: Edson Tirelli <ed.tirelli(a)gmail.com&gt; Subject: Re: [rules-users] Basic doubt regarding Drools Fusion - @expires To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Date: Thursday, March 17, 2011, 10:47 AM To be honest, I believe so, but didn't profiled it extensively.

I googled it quite a bit and I think it’s a path to be explored, albeit I’ve saw several messages on the mailing list regarding performance issues when using fireUntilHalt. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org<http://mc/compose?to=rules-users@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli JBoss Drools Core Development JBoss by Red Hat @ www.jboss.com -----Inline Attachment Follows----- _______________________________________________ rules-users mailing list rules-users@lists.jboss.org<http://mc/compose?to=rules-users@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
