Emanuele Mariani commented on JBRULES-3123:
-------------------------------------------

Hi,
I had the same problem and with debug I discover that the new approch to create a ProcessBuilder is to use a "org.jbpm.process.builder.ProcessBuilderFactoryServiceImpl" (row 26 of ProcessBuilderFactory).

Searching on all the parents pom.xml of knoledge-api I see that drools project is composed by drools api and jbpm api and if i tried to include this dependency:
   <groupId>org.jbpm</groupId>
   <artifactId>jbpm-bpmn2</artifactId>
   <version>5.1.0.Final</version>
With this inclusion the ProcessBuilderFactory find the ProcessBuilderFactoryServiceImpl on the classpath and all work correctly.

So, I suppose that is only a problem of not proper dependency management.

I hope I helped
Bye

> 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
