> 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
> Thread [main] (Suspended)
