      long duration = System.currentTimeMillis() - start;
    log.severe("isProcessRunning: " +  duration);

        private byte[] fetchProcessResource(ProcessInstance pi, String resourceName) {
            ProcessEngine processEngine = getProcessEngine(ProcessToolContext.Util.getThreadProcessToolContext());
            RepositoryService service = processEngine.getRepositoryService();


            ExecutionService executionService = processEngine.getExecutionService();
            org.jbpm.api.ProcessInstance processInstanceById = executionService.findProcessInstanceById(pi.getInternalId());
            String processDefinitionId;
            if (processInstanceById == null) { //look in history service
