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

[Mario Fusco (JIRA)]

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

Mario Fusco resolved DROOLS-93.
-------------------------------

    Fix Version/s: 5.6
                   6.0.0.Beta1
       Resolution: Done


The problem was actually caused by a wrong package name in the drl used in the provided test. I fixed the NPE by generating a proper compilation failure message.

> 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
