    copied!<p>I facing problem with X-Fire-all-1.0 version jar. In our application we implemented webservices, for this we are using xfire-all-1.0.jar. Working fine with this. But some times on our Jboss console getting following exceptions. This is I am not getting always. As per my application requirement, when client sends the request to get list of merchants details [Our webservice returns the all the merchant details in success scenario] response document is preparing with the help of x-fire api. But some times getting following issue. How to resolve it.Is the bug in xfire-all-1.0.jar?</p> <pre><code>java.util.ConcurrentModificationException at org.jdom.ContentList$FilterListIterator.checkConcurrentModification(ContentList.java:940)
