project_key: SOA

As the jcr*.jar has been removed from SOA-P 5.1.0 as a result of SOA-2206, we should also remove the JCR Node mapping from jbpm.varmapping.xml:

    <!-- JSR 170 JCR Node -->
    <jbpm-type>
      <matcher>
        <bean class="org.jbpm.context.exe.matcher.JcrNodeMatcher" />
      </matcher>
      <variable-instance class="org.jbpm.context.exe.variableinstance.JcrNodeInstance" />
    </jbpm-type>   

Otherwise, an attempt to persist a jBPM variable which is not handled by any of the other matchers (eg. a non-serializable POJO), results in the following failure:
