Concurrency problem in workflow cache

    XMLWordPrintable

Details

    Description

      The OSWorkflow manager uses a HashSet for caching. The trouble is that the hashset is not cloned when it is returned, so if it is updated, the code that is iterating over the cache can get a ConcurrentModificationException.
