service task workitemhandler node parsing error in JBDS

Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Create workitemhandler in JBDS as follows...
public void executeWorkItem(WorkItem workItem, WorkItemManager manager)

{ // extract parameters String snd_message = (String) workItem.getParameter("SecondMessage"); System.out.println("Prabakar ::: " + snd_message); Map<String,Object> results = new HashMap<String,Object>(); results.put("Result", "Ak"); manager.completeWorkItem(workItem.getId(), results); }

2.Update your workitemdefinition information as follows...
[
"name" : "SecondNotification",
"parameters" : [
"SecondMessage" : new StringDataType(),
],
"results" :[
"Result" : new StringDataType()
],
[
"icon" : "com/icon/world.png",
"displayName" : "Get"
]
3. Call the process in main method in JBDS
public static final void main(String[] args) {
try

{ KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.getKieClasspathContainer(); KieSession kSession = kContainer.newKieSession("ksession-process"); kSession.getWorkItemManager().registerWorkItemHandler("SecondNotification", new SecondWorkingHandler()); Map<String, Object> params = new HashMap<String, Object>(); params.put("MyResultParam", "Prabakar"); kSession.startProcess("com.sample.bpmn.hello", params); }

catch (Throwable t)

{ t.printStackTrace(); }

}
