Re: [rules-users] Unexpected java.lang.NullPointerException at org.drools.core.util.RightTupleIndexHashTable.removeAdd(RightTupleIndexHashTable.java:353)

Dear drools-users and team! My working for years code cease to work after switching from Drools 5.3.0Final to 5.4.0Final. Here is a rule of interest: .......................................................................... rule "Subscenario-Start" dialect "java" when act: Subscenario( status == "START", $super_run: super_run, $run: run ) then Scenario scenario = (Scenario) DroolsTab.mapInstance( act.sub_scenario ); scenario.run = new Integer ( runcount.intValue() + 1 ); scenario.super_run = $super_run; scenario.caller = $run; scenario.status = "START"; if ( traceLevel.intValue() > 0 ) System.out.println( "STARTING SUB-SCENARIO "+scenario.title+" "+scenario.run ); Map acm = contexToMap( act.context ); Map scm = contexToMap( scenario.context ); Map rmp = replace( act.ctxmap, acm ); scenario.ctxmap = replace( scm, rmp ); System.out.println( "1" ); if ( act.repeat != null ) { if ( act.step == null ) act.step = new Integer( 0 ); repeatStep( act, scenario.ctxmap, act.step.intValue() ); } System.out.println( "2" ); insert( scenario ); System.out.println( "3 "+act.wait_subscenario ); if ( act.wait_subscenario != null && act.wait_subscenario.booleanValue() ) act.status = "REPEAT"; else act.status = "DONE"; System.out.println( "4 "+act.status ); act.sub_run = scenario.run; update( act ); System.out.println( "5" ); DroolsTab.getWorkingMemory().setGlobal( "runcount", scenario.run ); System.out.println( "6" ); end .......................................................................... Here is a trace (Please note: The first time it worked, and the second gave an error): .......................................................................... ru@ru-desktop ~ $ DroolsTabScene-5.2/run_protege.sh WARNING: missing bundle: protege_text -- BundleHelper. <init> () Loaded 5000 instances: Scenario_ProjectKB_Class20011 OpenMap(tm) Version 5.0 Copyright (C) BBNT Solutions LLC.
