In stream mode it is necessary to enforce flushing of path memories. However doing this on an unlinked path is a waste of time and moreover can causes a NPE in presence of a subnetwork like the following:
java.lang.NullPointerException at org.drools.core.phreak.RuleNetworkEvaluator.deleteChildLeftTuple(RuleNetworkEvaluator.java:725) at org.drools.core.phreak.RuleNetworkEvaluator.unlinkAndDeleteChildLeftTuple(RuleNetworkEvaluator.java:718) at org.drools.core.phreak.PhreakJoinNode.doLeftDeletes(PhreakJoinNode.java:418) at org.drools.core.phreak.PhreakJoinNode.doNode(PhreakJoinNode.java:47) at org.drools.core.phreak.RuleNetworkEvaluator.switchOnDoBetaNode(RuleNetworkEvaluator.java:519) at org.drools.core.phreak.RuleNetworkEvaluator.evalBetaNode(RuleNetworkEvaluator.java:505) at org.drools.core.phreak.RuleNetworkEvaluator.evalNode(RuleNetworkEvaluator.java:341) at org.drools.core.phreak.RuleNetworkEvaluator.innerEval(RuleNetworkEvaluator.java:301) at org.drools.core.phreak.RuleNetworkEvaluator.doRiaNode(RuleNetworkEvaluator.java:573) at org.drools.core.phreak.RuleNetworkEvaluator.evalBetaNode(RuleNetworkEvaluator.java:500) at org.drools.core.phreak.RuleNetworkEvaluator.evalNode(RuleNetworkEvaluator.java:341) at org.drools.core.phreak.RuleNetworkEvaluator.innerEval(RuleNetworkEvaluator.java:301) at org.drools.core.phreak.RuleNetworkEvaluator.outerEval(RuleNetworkEvaluator.java:136) at org.drools.core.phreak.RuleNetworkEvaluator.evaluateNetwork(RuleNetworkEvaluator.java:94) at org.drools.core.phreak.RuleExecutor.reEvaluateNetwork(RuleExecutor.java:194) at org.drools.core.phreak.RuleExecutor.evaluateNetworkAndFire(RuleExecutor.java:73) at org.drools.core.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:969) at org.drools.core.common.DefaultAgenda.fireLoop(DefaultAgenda.java:1311) at org.drools.core.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1250) at org.drools.core.impl.StatefulKnowledgeSessionImpl.internalFireAllRules(StatefulKnowledgeSessionImpl.java:1356) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:1347) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:1328)
