[jboss-jira] [JBoss JIRA] (DROOLS-5224) KieBase build fails with forall patterns containing "not equal" constraints on Dates

KieBase build fails with forall patterns containing "not equal" constraints on Dates ------------------------------------------------------------------------------------ Key: DROOLS-5224 URL: https://issues.redhat.com/browse/DROOLS-5224 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.33.0.Final, 7.34.0.Final, 7.35.0.Final Reporter: Matteo Casalino Assignee: Mario Fusco Priority: Major Attachments: forall-not-equal-constraint-on-dates.zip This is the same issue as https://issues.redhat.com/browse/DROOLS-5100, but on Dates. As of Drools 7.33.0.Final, forall patterns with "not equal" (!=) constraints on Dates will break when building the KieBase. For example the following DRL: {noformat} rule "forall with not equal" when forall(java.util.Date(this != "29-Dec-2019")) then end {noformat} generates the following error: {noformat} java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1967) at org.drools.core.rule.constraint.MvelConstraint.getLeftInExpression(MvelConstraint.java:608) at org.drools.core.rule.constraint.MvelConstraint.hashCode(MvelConstraint.java:602) at org.drools.core.reteoo.AlphaNode.calculateHashCode(AlphaNode.java:189) at org.drools.core.reteoo.AlphaNode.<init>(AlphaNode.java:89) at org.drools.core.reteoo.builder.PhreakNodeFactory.buildAlphaNode(PhreakNodeFactory.java:88) at org.drools.core.reteoo.builder.PatternBuilder.buildAlphaNodeChain(PatternBuilder.java:360) at org.drools.core.reteoo.builder.PatternBuilder.attachAlphaNodes(PatternBuilder.java:346) at org.drools.core.reteoo.builder.PatternBuilder.attachPattern(PatternBuilder.java:136) at org.drools.core.reteoo.builder.PatternBuilder.build(PatternBuilder.java:84) at org.drools.core.reteoo.builder.GroupElementBuilder$NotBuilder.build(GroupElementBuilder.java:220) at org.drools.core.reteoo.builder.GroupElementBuilder.build(GroupElementBuilder.java:68) at org.drools.core.reteoo.builder.GroupElementBuilder$AndBuilder.build(GroupElementBuilder.java:108) at org.drools.core.reteoo.builder.GroupElementBuilder.build(GroupElementBuilder.java:68) at org.drools.core.reteoo.builder.ReteooRuleBuilder.addSubRule(ReteooRuleBuilder.java:167) at org.drools.core.reteoo.builder.ReteooRuleBuilder.addRule(ReteooRuleBuilder.java:139) at org.drools.core.reteoo.ReteooBuilder.addRule(ReteooBuilder.java:110) at org.drools.core.impl.KnowledgeBaseImpl.internalAddRule(KnowledgeBaseImpl.java:1525) at org.drools.core.impl.KnowledgeBaseImpl.internalAddPackages(KnowledgeBaseImpl.java:926) at org.drools.core.impl.KnowledgeBaseImpl.lambda$addPackages$2(KnowledgeBaseImpl.java:728) at org.drools.core.impl.KnowledgeBaseImpl.enqueueModification(KnowledgeBaseImpl.java:745) at org.drools.core.impl.KnowledgeBaseImpl.addPackages(KnowledgeBaseImpl.java:728) at org.drools.compiler.kie.builder.impl.AbstractKieModule.createKieBase(AbstractKieModule.java:226) at org.drools.compiler.kie.builder.impl.KieContainerImpl.createKieBase(KieContainerImpl.java:407) at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKieBase(KieContainerImpl.java:375) {noformat} This is working fine when using Drools <= 7.32.0.Final.
