NPE while removing and adding same package
------------------------------------------

                 Key: JBRULES-550
                 URL: http://jira.jboss.com/jira/browse/JBRULES-550
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 3.0.4
         Environment: Windows
            Reporter: Ravi Godbole
         Assigned To: Mark Proctor


I am trying to reload the rule which is modified externally [ without stopping my rule engine which already has the mentioned rule loaded]. When adding is commented everything works well.

// Code snippet as follows

			ruleBase = RuleBaseFactory.newRuleBase();
			
			final Reader source = new InputStreamReader( RuleService.class.getResourceAsStream("/rules/" + "TestAddNew.drl" ) );
	    	
	        PackageBuilder builder = new PackageBuilder();
	        builder.addPackageFromDrl( source );
	        ruleBase.addPackage( builder.getPackage() );
			
			workingMemory = ruleBase.newWorkingMemory( );
			
			workingMemory.assertObject(new Object());
			
			ruleBase.removePackage("com.test.one");
			
			final Reader sourceOne = new InputStreamReader( RuleService.class.getResourceAsStream("/rules/" + "TestAddNew.drl" ) );
			
	        PackageBuilder builder_1 = new PackageBuilder();
	        builder_1.addPackageFromDrl( sourceOne );
	        ruleBase.addPackage( builder_1.getPackage() );
	        
	        System.out.println("Rule successfully Added");

///////////// Rule file //////////////////////////


package com.test.one

import java.lang.Object;

rule addNewRule
no-loop true
   when
  	eval( 1 > 2 ) 
   then
	System.out.println("True evaluated");
end
