Error description
When IBM Business Process Manager (BPM) tries to cache managed asset class loaders for its process applications, exceptions might appear in the SystemOut.log file showing a stack like the following example: Caused by: java.util.ConcurrentModificationException at java.util.LinkedHashMap$AbstractMapIterator.checkConcurrentMod(L inkedHashMap.java:136) at java.util.LinkedHashMap$AbstractMapIterator.makeNext(LinkedHashM ap.java: 141) at java.util.LinkedHashMap$KeyIterator.next(LinkedHashMap.j ava:201) at com.lombardisoftware.server.core.ManagedAssetClassLoader.toStrin g(Manage dAssetClassLoader.java:185) at java.lang.String.valueOf(String.java:1569) at java.lang.StringBuilder.append(StringBuilder.java:194) PRODUCTS AFFECTED IBM BPM Advanced IBM BPM Standard IBM BPM Express
Local fix
Problem summary
Interim fix JR54100 introduced code that iterates over a collection of all managed asset class loaders. If a different thread adds an entry to the collection at the same time, you receive a concurrentModification exception.
Problem conclusion
A fix is available on top of IBM BPM fix pack 8.0.1.3 and is currently targeted for inclusion in IBM BPM 8570 CF2017.03 that changes the fix code introduced by JR54100 to be thread-safe.
