Anton Giertli created DROOLS-1178: ------------------------------------- Summary: NPE removing a not initialized rule in stream mode Key: DROOLS-1178 URL: https://issues.jboss.org/browse/DROOLS-1178 Project: Drools Issue Type: Bug Reporter: Anton Giertli Assignee: Mario Fusco In Stream mode a path memory can have a RuleAgendaItem even if the path has been never totally linked and then it misses the first segment memory. When an incremental compilation tries to remove the rule for that path the following exception is thrown: {code} java.lang.NullPointerException at org.drools.core.phreak.RuleNetworkEvaluator.evaluateNetwork(RuleNetworkEvaluator.java:70) at org.drools.core.phreak.AddRemoveRule.flushStagedTuples(AddRemoveRule.java:547) at org.drools.core.phreak.AddRemoveRule.removeRule(AddRemoveRule.java:178) at org.drools.core.reteoo.ReteooBuilder.removeTerminalNode(ReteooBuilder.java:185) at org.drools.core.reteoo.ReteooBuilder.removeRules(ReteooBuilder.java:170) at org.drools.core.impl.KnowledgeBaseImpl.internalRemoveRule(KnowledgeBaseImpl.java:1685) at org.drools.core.impl.KnowledgeBaseImpl.access$200(KnowledgeBaseImpl.java:117) at org.drools.core.impl.KnowledgeBaseImpl$3.run(KnowledgeBaseImpl.java:1658) at org.drools.core.impl.KnowledgeBaseImpl.enqueueModification(KnowledgeBaseImpl.java:720) at org.drools.core.impl.KnowledgeBaseImpl.removeRule(KnowledgeBaseImpl.java:1655) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.preProcessRules(KnowledgeBuilderImpl.java:1155) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.compileRules(KnowledgeBuilderImpl.java:1106) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.compileAllRules(KnowledgeBuilderImpl.java:989) at org.drools.compiler.builder.impl.CompositeKnowledgeBuilderImpl.buildRules(CompositeKnowledgeBuilderImpl.java:260) at org.drools.compiler.builder.impl.CompositeKnowledgeBuilderImpl.buildPackages(CompositeKnowledgeBuilderImpl.java:121) at org.drools.compiler.builder.impl.CompositeKnowledgeBuilderImpl.build(CompositeKnowledgeBuilderImpl.java:105) at org.drools.compiler.kie.builder.impl.KieContainerImpl.rebuildAll(KieContainerImpl.java:386) at org.drools.compiler.kie.builder.impl.KieContainerImpl.updateKBase(KieContainerImpl.java:241) at org.drools.compiler.kie.builder.impl.KieContainerImpl.access$000(KieContainerImpl.java:80) at org.drools.compiler.kie.builder.impl.KieContainerImpl$1.run(KieContainerImpl.java:186) at org.drools.core.impl.KnowledgeBaseImpl.enqueueModification(KnowledgeBaseImpl.java:720) at org.drools.compiler.kie.builder.impl.KieContainerImpl.update(KieContainerImpl.java:183) at org.drools.compiler.kie.builder.impl.KieContainerImpl.updateToVersion(KieContainerImpl.java:130) at org.drools.compiler.integrationtests.incrementalcompilation.IncrementalCompilationTest.testRemoveRuleWithNonInitializedPath(IncrementalCompilationTest.java:2832) {code} -- This message was sent by Atlassian JIRA (v6.4.11#64026)
