Error description
When you use the group management capability of the Process Admin Console, a JavaScript API, or a REST API to add group memberships, IBM Business Process Manager (BPM) does not verify that there are no circular references. As a result, task assignments fail with an StackOverflowError when a circular group membership is found. These are the errors that are logged CWLLG2015E: An unexpected runtime exception occurred. See exception for more details.

Local fix
Problem summary
You may model circular group memberships in the following ways: - Using the Process Admin Console, the User Management > Group Management tab and click Add Groups. - Using the Group Resource of the REST API. See ?REST interface for BPD-related resources - Group Resource - PUT Method? at https://www.ibm.com/support/knowledgecenter/SSFPJS_8.5.5/com.ibm .wbpm.ref.doc/rest/bpmrest/rest_bpm_wle_v1_group_groupnameorid_ put.htm?lang=en. - Using tw.system.org.findRoleByName.addRoles of the JavaScript API. See ?JavaScript API for IBM Process Designer? at https://www.ibm.com/support/knowledgecenter/SSFPJS_8.5.5/com.ibm .wbpm.ref.doc/ae/doc/JSAPI.html?lang=en. If you created a circular group reference in one of these ways you, do not get an immediate exception. When a task is created and the associated group is resolved, you see a StackOverflowException similar to the following exception if the group contains a circular group membership: FFDC Exception:java.lang.StackOverflowError SourceId:com.ibm.ws.uow.UOWManagerImpl.runUnderNewUOW ProbeId:944 Reporter:com.ibm.ws.uow.UOWManagerImpl@4e179214 java.lang.StackOverflowError at java.util.HashMap.hash(HashMap.java:136) at java.util.HashMap.getEntry(HashMap.java:587) at java.util.HashMap.get(HashMap.java:575) at com.lombardisoftware.core.cache.GenericCache.getCacheData (GenericCache.java:161) at com.lombardisoftware.server.core.cache.

Problem conclusion
A fix is/will be available that checks whether a group membership cycle is created when members are added to a group. If a group membership cycle is detected, you see a specific error in the Process Admin Console and the new member is not added to the group. On Fix Central (http://www.ibm.com/support/fixcentral), search for JR52494: 1. Select IBM Business Process Manager with your edition from the product selector, the installed version to the fix pack level, and your platform, and then click Continue. 2. Select APAR or SPR, enter JR52494, and click Continue. When you download fix packages, ensure that you also download the readme file for each fix. Review each readme file for additional installation instructions and information about the fix.
