[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1747) Null pointer exception from AbstractRuleBase.addPackage when loading rules scoped with parens

[Edson Tirelli (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBRULES-1747?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Edson Tirelli closed JBRULES-1747.
----------------------------------

    Resolution: Done


I was not able to reproduce this problem with the new parser, used since Drools 5 M3. I added a test case to the code base anyway and I am closing this ticket. If you run into this problem again, please re-open the ticket.

Thanks for reporting,
Edson

> The drl below produces a null pointer exception when calling ruleBase.addPackage(Drl). If the extra parens after the "||" are removed the exception doesn't occur. The rule compiles and runs successfully in 5.0M1.
