Subject [jira] Created: (CXF-2503) ConcurrentModificationException thrown by AttachmentDeserializer
Date Tue, 27 Oct 2009 22:48:59 GMT
ConcurrentModificationException thrown by AttachmentDeserializer
----------------------------------------------------------------

                 Key: CXF-2503
                 URL: https://issues.apache.org/jira/browse/CXF-2503
             Project: CXF
          Issue Type: Bug
          Components: Core
            Reporter: William Tam


The follow stack (based on 2.2.x source) shows AttachmentDeserializer.cacheStreamedAttachments
(1) is looping on the LazyAttachmentCollection.attachments List.

for (Attachment a : attachments.getLoadedAttachments()) {
 ...
}

And, DelegatingInputStream.close() (2) triggers LazyAttachmentCollection.hasNext() (3) to
insert new item to LazyAttachmentCollection.attachments List which causes ConcurrentModificationException
