Description of problem: There is a regression with the REST endpoint, POST /hawkular/metrics/m/stats/query which is used for rendering graphs for deployments, statefulsets, etc. It fails with an NPE in SimpleTagQueryParser. Here is the stack trace from a recent log: 2018-05-23 03:33:13,357 ERROR [org.hawkular.metrics.api.jaxrs.util.ApiUtils] (RxComputationScheduler-3) HAWKMETRICS200010: Failed to process request: java.lang.NullPointerException at org.hawkular.metrics.core.service.tags.SimpleTagQueryParser.lambda$tagValueFilter$40(SimpleTagQueryParser.java:557) at rx.internal.operators.OnSubscribeFilter$FilterSubscriber.onNext(OnSubscribeFilter.java:67) at rx.internal.operators.OnSubscribeFilter$FilterSubscriber.onNext(OnSubscribeFilter.java:76) at rx.internal.operators.OperatorMerge$MergeSubscriber.emitScalar(OperatorMerge.java:395) at rx.internal.operators.OperatorMerge$MergeSubscriber.tryEmit(OperatorMerge.java:355) at rx.internal.operators.OperatorMerge$InnerSubscriber.onNext(OperatorMerge.java:846) at rx.internal.operators.OnSubscribeDoOnEach$DoOnEachSubscriber.onNext(OnSubscribeDoOnEach.java:101) at rx.observers.Subscribers$5.onNext(Subscribers.java:235) at rx.internal.operators.OnSubscribeSwitchIfEmpty$ParentSubscriber.onNext(OnSubscribeSwitchIfEmpty.java:121) at rx.internal.operators.OnSubscribeMap$MapSubscriber.onNext(OnSubscribeMap.java:77) at rx.internal.operators.OperatorMerge$MergeSubscriber.emitScalar(OperatorMerge.java:395) at rx.internal.operators.OperatorMerge$MergeSubscriber.tryEmit(OperatorMerge.java:355) at rx.internal.operators.OperatorMerge$InnerSubscriber.onNext(OperatorMerge.java:846) at org.hawkular.rx.cassandra.driver.ResultSetToRowsTransformer$RowProducer.produce(ResultSetToRowsTransformer.java:111) at org.hawkular.rx.cassandra.driver.ResultSetToRowsTransformer$RowProducer.lambda$execute$0(ResultSetToRowsTransformer.java:154) at rx.internal.schedulers.EventLoopsScheduler$EventLoopWorker$1.call(EventLoopsScheduler.java:172) at rx.internal.schedulers.ScheduledAction.run(ScheduledAction.java:55) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: rx.exceptions.OnErrorThrowable$OnNextValue: OnError while emitting onNext value: org.hawkular.metrics.model.Metric.class at rx.exceptions.OnErrorThrowable.addValueAsLastCause(OnErrorThrowable.java:118) at rx.internal.operators.OnSubscribeFilter$FilterSubscriber.onNext(OnSubscribeFilter.java:71) ... 22 more This is a new regression as a result of changes made in SimpleTagQueryParser for 3.10.
