I am using Java Serice Task to get and set some processing variables. something like this.
public class CustomDelegate implements JavaDelegate {
public void execute(DelegateExecution execution) throws Exception {
//Counter
int i= (Integer)execution.getVariable("count");
if(i<5) { i= i+ 1;
execution.setVariable("count", i);
}
//External call
String orderID= (String) execution.getVariable("orderID");
String status= MyUtil.getStatus(orderID);
execution.setVariable("status", status);
}}
We have multiple orders and so mutliple threads. As recommended in userguide - we are not using any member variables. But using local variables. But the last sentence in user guide says [red] class must be thread-safe[/red] too. Do we still need to make our custom javadelegate thread safe(using synchronize) ? Is it because references to variables are mutable?
