Hello hps-software, Using the most recent build of hps-java, we obtain the following error during event processing on the monitoring application in the counting house: SEVERE: Error making ECal hits > java.lang.NullPointerException > at org.hps.evio.ECalEvioReader.makePulseHits(ECalEvioReader.java:259) > at org.hps.evio.ECalEvioReader.makeHits(ECalEvioReader.java:129) > at > org.hps.evio.LCSimEngRunEventBuilder.makeLCSimEvent(LCSimEngRunEventBuilder.java:47) > at > org.hps.record.composite.LcioEventAdapter.recordSupplied(LcioEventAdapter.java:82) > at > org.freehep.record.loop.DefaultRecordLoop.consumeRecord(DefaultRecordLoop.java:832) > at > org.freehep.record.loop.DefaultRecordLoop.loop(DefaultRecordLoop.java:668) > at > org.freehep.record.loop.DefaultRecordLoop.execute(DefaultRecordLoop.java:566) > at org.hps.record.composite.CompositeLoop.loop(CompositeLoop.java:211) > at > org.hps.record.composite.EventProcessingThread.run(EventProcessingThread.java:48) > It seems to be keeping us from seeing events in some of the GUIs. Any ideas what the problem is?
