Steps to Reproduce


Root Cause

A defect in Pegasystems’ code or rules.  A check needs to be inserted to make sure the thread about to be removed exists. 


Perform the following local-change:
  1. Copy CPMRemoveThread to one of your own rulesets. The code of step 2 of this activity currently is:
if (!sCurrentThreadName.equals(sThreadName) )

2. Change this step to the following: 
int appNameIndex = -1;
String appName = null;
if (!sCurrentThreadName.equals(sThreadName) ) {
                if (sCurrentThreadName != null && (appNameIndex = sCurrentThreadName.indexOf("/$")) > 0) {
                                appName = sCurrentThreadName.substring(0, appNameIndex);
                                if((sThreadName != null) && (!(sThreadName.indexOf(appName) >= 0))) {
                                                // If there's an appname in the thread name, retain same form
                                                sThreadName = appName + "/$" + sThreadName;
                PRThread inactiveThread = tools.getThread().getRequestor().getThread(sThreadName);
                if (inactiveThread != null) {
