I have spring config (JBPM 5.0 release):

<context:annotation-config/>

    <bean id="processBuilderFactoryService" class="org.jbpm.process.builder.ProcessBuilderFactoryServiceImpl"/>

I start some process instance in this StatefulKnowledgeSession session. Main thread is bloked in startProcess() while process instance not finish. When I try start process instance in child thread, but I can not get process from knowledge base: getKnowledgeBase().getProcess(processId). Main thread is blocked. What`s this? I wait more from jbpm 5. Where is parallel processes?
