Since Shark does not start a new thread, your application must, for 
scenario you described.

       //final SharkConnection sc;
       //final Map workflowRelevantData;
       for (int i = 0; i < 5; i++) {
          new Thread() {
             public void run() {
                try {
                   WfProcess theProcess = sc.createProcess("pkg","pdef");
                   theProcess.set_process_context(workflowRelevantData);
                   theProcess.start();
                } catch (RootException e) {
                   e.printStackTrace();
                }
             }
          }.start();
       }
