Hello, I keep trying to migrate drools from 5.5 to 6 on my project. I found a second regression/issue. I'm trying to produce a unit test for 6.1.0-SNAPSHOT but I face some difficulties to determine the cause of this issue. So I have a drl with 3 rules. I'm a bit disappointed because if I switch two rules (without modifying anything, just switch one rule with another in the drl file), the NPE disappears... Here is the stacktrace: java.lang.NullPointerException at org.drools.core.util.index.LeftTupleIndexHashTable.remove(LeftTupleIndexHashTable.java:386) at org.drools.core.phreak.RuleNetworkEvaluator.doUpdatesReorderLeftMemory(RuleNetworkEvaluator.java:799) at org.drools.core.phreak.PhreakJoinNode.doNode(PhreakJoinNode.java:38) at org.drools.core.phreak.RuleNetworkEvaluator.switchOnDoBetaNode(RuleNetworkEvaluator.java:547) at org.drools.core.phreak.RuleNetworkEvaluator.evalBetaNode(RuleNetworkEvaluator.java:533) at org.drools.core.phreak.RuleNetworkEvaluator.innerEval(RuleNetworkEvaluator.java:334) at org.drools.core.phreak.RuleNetworkEvaluator.outerEval(RuleNetworkEvaluator.java:161) at org.drools.core.phreak.RuleNetworkEvaluator.evaluateNetwork(RuleNetworkEvaluator.java:116) at org.drools.core.phreak.RuleExecutor.reEvaluateNetwork(RuleExecutor.java:201) at org.drools.core.phreak.RuleExecutor.evaluateNetworkAndFire(RuleExecutor.java:68) at org.drools.core.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:935) at org.drools.core.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1200) at org.drools.core.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:952) at org.drools.core.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:926) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:232) at org.drools.core.command.runtime.rule.FireAllRulesCommand.execute(FireAllRulesCommand.java:106) at org.drools.core.command.runtime.rule.FireAllRulesCommand.execute(FireAllRulesCommand.java:32) at org.drools.core.command.runtime.BatchExecutionCommandImpl.execute(BatchExecutionCommandImpl.java:155) at org.drools.core.command.runtime.BatchExecutionCommandImpl.execute(BatchExecutionCommandImpl.java:76) at org.drools.core.impl.StatelessKnowledgeSessionImpl.execute(StatelessKnowledgeSessionImpl.java:334) -- View this message in context: http://drools.46999.n3.nabble.com/NullPointerException-with-LeftTupleInde...
