Sometimes this works and sometimes it doesn't

System

I have a java helper class that I call from a workflow that returns a coma delmited string containing a list of UDA names. My problem is that this works sometimes and others it throws a null pointer exception.

Code for the class....

System.out.println("*****************************************");
System.out.println("* Starting getUDAS v0.1, by Chris Bland *");
System.out.println("*****************************************");
WorkflowProcess wp = null;
long pID = getProcessId();
Workspace workspace = getWorkspace();
WorkflowNamedUdaAccessor objWFNUDA = null;
Collection objCollection = null;
Map objmap = null;


try {
wp = workspace.getWorkflowProcessById(pID);
objWFNUDA = wp.getUdas();
objCollection = objWFNUDA.getWorkflowUserDefinedAttributeCollection();
objmap = objWFNUDA.getWorkflowUserDefinedAttributeMap();
}

catch(Exception e) {
System.out.println("Error While retrieving UDAS: " + e );

}

System.out.println("*************************");
System.out.println("* Getting Attribute Map *");
System.out.println("*************************");
System.out.println(objmap.keySet());


String strResults = objmap.keySet().toString();

strResults = strResults.substring(1, strResults.length() -1);
strResults = strResults.replaceAll(", ", ",");
System.out.println("UDAs returned are :" + strResults);

//Cleanup
wp = null;
objWFNUDA = null;
objCollection = null;
objmap =null;
//Return UDAs in a comma delimited string
return(strResults);
}

}
