[jboss-jira] [JBoss JIRA] (DROOLS-93) Building rule file that contains event declaration with @duration ends with NPE

[Petr Široký (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-93?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Petr Široký updated DROOLS-93:
------------------------------

    Description: 
Building kbase with simple rule file with event declaration that has a @duration attribute ends with NPE. When the @duration is removed, file is built correctly. See attached maven reproducer (just run mvn test).

The rule file looks like this:
{code}
package org.jboss.drools.example.kbase

declare org.jboss.drools.example.kbase.SimpleFact
    @role(event)
    @duration(duration)
end
{code}

Exception thrown when building the file:
{code}
java.lang.NullPointerException
