[jboss-jira] [JBoss JIRA] Commented: (JBRULES-3123) [Regression] .rf file raises a null pointer exception when it is loaded

[Kris Verlaenen (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-3123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631269#comment-12631269 ] 

Kris Verlaenen commented on JBRULES-3123:
-----------------------------------------

The problem is that the drools core modules don't really require jbpm5 modules, they are only needed once you start doing RuleFlow.  That is why they are not added as requirements in the pom of those modules.  Some drools modules that combine rules with processes (e.g. in the droolsjbpm-integration repository) do have a dependency to the necessary jbpm modules in their pom.  But if you want to use RuleFlow, it's probably best to add dependencies to both the drools and jbpm modules in your pom.

> I have just switched from version 5.1.1 to 5.2.0.Final
> I have a ruleflow (.rf) file which can be loaded. I have the following stack trace :
> java.lang.NullPointerException
> 	at org.drools.compiler.PackageBuilder.addProcessFromXml(PackageBuilder.java:516)
> 	at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:556)
> 	at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28)
> 	at com.ariadnext.NewDroolsTest$RulesUtils.loadRules(NewDroolsTest.java:107)
> I made a simple junit test which reproduces the bug.
