Local fix
Problem summary
If a group in the user registry and an IBM BPM internal group share the same name, a user who is member of the user registry group is added as member of the internal group when he or she logs in. IBM BPM V8.5.7 CF 2017.06 contains a regression where the .roles method of a JavaScript TWUser object could cause a NullPointerException: JavaScriptRun E CWLLG2015E: An unexpected runtime exception occurred. See exception for more details. Error: Wrapped java.lang.NullPointerException (<JSScript>#11). org.mozilla.javascript.WrappedException: Wrapped java.lang.NullPointerException (<JSScript>#11) at org.mozilla.javascript.Context.throwAsScriptRuntimeEx(Context.ja va:1754) at org.mozilla.javascript.MemberBox.invoke(MemberBox.java:148) at org.mozilla.javascript.ScriptableObject$GetterSlot.getValue(Scri ptableObject.java:295) at org.mozilla.javascript.ScriptableObject.get(ScriptableObject.jav a:456) at org.mozilla.javascript.ScriptableObject.getProperty(ScriptableOb ject.java:2185) at org.mozilla.javascript.ScriptRuntime.getObjectProp(ScriptRuntime .java:1492) at org.mozilla.javascript.ScriptRuntime.getObjectProp(ScriptRuntim. java:1485): Caused by: java.lang.NullPointerException at com.lombardisoftware.core.script.js.Utilities$RoleAdapter.getPro jectName(Utilities.java:2045) at com.lombardisoftware.core.script.js.Utilities.updateDisplayNames (Utilities.java:1912) at com.lombardisoftware.core.script.js.Utilities.updateUserGroups(U tilities.java:1881) at com.lombardisoftware.core.script.js.objects.UserScriptable.jsGet _roles(UserScriptable.java:298)
Problem conclusion
A fix that prevents internal groups from being updated when users log in will be included in IBM BPM V7.5.12, V8.0.1.3, V8.5.0.2, V8.5.5.0, V8.5.6.0 CF02, and future releases. A fix is available for V8.5.7 cumulative fix 2017.06 that corrects this issue and the .roles NullPointerException regression introduced in IBM BPM V8.5.7 CF 2017.06.
