I have spring config (JBPM 5.0 release):

<context:annotation-config/>

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

    <bean id="processMarshallerFactoryService" class="org.flexpay.common.process.marshaller.ProcessMarshallerFactoryServiceImpl"/>

    <bean id="processRuntimeFactoryService" class="org.jbpm.process.instance.ProcessRuntimeFactoryServiceImpl"/>

    <bean id="bpmn2ProcessProvider" class="org.jbpm.bpmn2.BPMN2ProcessProviderImpl"/>

    <bean name="initProcessBuilderFactory" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
        <property name="staticMethod" value="org.drools.compiler.ProcessBuilderFactory.setProcessBuilderFactoryService"/>
        <property name="arguments">
            <list>
                <ref bean="processBuilderFactoryService"/>
            </list>
       </property>
    </bean>

    <bean name="initProcessMarshallerFactory" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
        <property name="staticMethod" value="org.drools.marshalling.impl.ProcessMarshallerFactory.setProcessMarshallerFactoryService"/>
        <property name="arguments">
            <list>
                <ref bean="processMarshallerFactoryService"/>
            </list>
       </property>
    </bean>

    <bean name="initProcessRuntimeFactory" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
        <property name="staticMethod" value="org.drools.runtime.process.ProcessRuntimeFactory.setProcessRuntimeFactoryService"/>
        <property name="arguments">
            <list>
                <ref bean="processRuntimeFactoryService"/>
            </list>
       </property>
    </bean>

    <bean name="initBPMN2ProcessFactory" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" >
        <property name="staticMethod" value="org.drools.compiler.BPMN2ProcessFactory.setBPMN2ProcessProvider"/>
        <property name="arguments">
            <list>
                <ref bean="bpmn2ProcessProvider"/>
            </list>
       </property>
    </bean>

    <drools:kstore id="knowledgeStore" />

<drools:kbase id="knowledgeBase">
        <drools:resources>
         </drools:resources>
        <drools:configuration>
        </drools:configuration>
    </drools:kbase>

<drools:ksession id="jpaSingleSessionCommandService" type="stateful" kbase="knowledgeBase">
        <drools:configuration>
            <drools:jpa-persistence load="1">
                <drools:transaction-manager ref="transactionManager" />
                <drools:entity-manager-factory ref="entityManagerFactory" />
            </drools:jpa-persistence>
        </drools:configuration>
    </drools:ksession>

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?
