We currently have a process that I am attempting to load into a KnowledgeBuilder. The process has 3 embedded subprocesses, each one having a start node. The main process has one start node and another message start node. When loading into KnowledgeBuilder, I am getting the following exception:

java.lang.IllegalArgumentException: A RuleFlowProcess cannot have more than one start node!
          at org.jbpm.ruleflow.core.RuleFlowProcess$WorkflowProcessNodeContainer.validateAddNode(RuleFlowProcess.java:81)
          at org.jbpm.workflow.core.impl.NodeContainerImpl.addNode(NodeContainerImpl.java:42)
          at org.jbpm.workflow.core.impl.WorkflowProcessImpl.addNode(WorkflowProcessImpl.java:63)
          at org.jbpm.bpmn2.xml.AbstractNodeHandler.end(AbstractNodeHandler.java:110)


A little Googling led me to this issue in JIRA:  https://issues.jboss.org/browse/JBPM-3586 https://issues.jboss.org/browse/JBPM-3586

I tried loading the multiple-incomes.bpmn attached in the JIRA issue and I am getting the same error. The resolution does say that it is implemented as of June 6, 2012 and should make it's way to JBPM 5.4 with a note: "support for multiple start events with restriction that only one can be with no event definition". I attempted to use the snapshot build (5.4.0-SNAPSHOT) by adding the following to my pom.xml

    <repositories>
        <repository>
            <id>repository.jboss.org</id>
            <name>JBoss Repository - Snapshots</name>
            <url> http://snapshots.jboss.org/maven2 http://snapshots.jboss.org/maven2</url>
            <layout>default</layout>
            <releases>
                <enabled>false</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
                <updatePolicy>never</updatePolicy>
            </snapshots>
        </repository>
    </repositories>

I am however getting the same error when I load the file. Has anyone experienced a similar issue or at least can provide information on how to get a version that has the fix for this?

Thanks in advance the help.
