We are maintaining an application that heavily relies on DOM4J and Xpath. Once in a while we see a strange behaviors with results of XPath execution via DOM4J: The text result would simply be truncated.
We tried applying the recommendation provided here: http://www.mail-archive.com/dom4j-user@lists.sourceforge.net/msg02688.html
It seems the problem occurs less frequently but it still manifests itsself. Last time we got it, it was after applying Xpath on a the clone of a document parsed as indicated by the previous link.
This also seems to be similar to the issue mentioned here: Use of text() function when using xPath in dom4j
