Re: [rules-users] ClassCastException during inserting knowledge package

I've downloaded last stable build (number 3845, made 2010-04-14) from Drools Hudson (http://hudson.jboss.org/hudson/job/drools/). After running my tests I got same problem (but little different StackTrace): java.lang.ClassCastException: org.drools.core.util.ObjectHashMap at org.drools.reteoo.AlphaNode.updateSink(AlphaNode.java:172) at org.drools.reteoo.BetaNode.attach(BetaNode.java:214) at org.drools.reteoo.builder.BuildUtils.attachNode(BuildUtils.java:160) at org.drools.reteoo.builder.GroupElementBuilder$NotBuilder.build(GroupElementBuilder.java:281) at org.drools.reteoo.builder.GroupElementBuilder.build(GroupElementBuilder.java:77) at org.drools.reteoo.builder.GroupElementBuilder$AndBuilder.build(GroupElementBuilder.java:130) at org.drools.reteoo.builder.GroupElementBuilder.build(GroupElementBuilder.java:77) at org.drools.reteoo.builder.ReteooRuleBuilder.addSubRule(ReteooRuleBuilder.java:155) at org.drools.reteoo.builder.ReteooRuleBuilder.addRule(ReteooRuleBuilder.java:128) at org.drools.reteoo.ReteooBuilder.addRule(ReteooBuilder.java:117) at org.drools.reteoo.ReteooRuleBase.addRule(ReteooRuleBase.java:409) at org.drools.common.AbstractRuleBase.addRule(AbstractRuleBase.java:638) at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:520) at org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:426) at org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:121) Maybe I should download Drools from other place?
