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
