After working some time ( e.g. 2 hours) suddenly when I try to open an file (xhtml or xml) occurs the error that make unable to edit the file using jbosstools. Using other tools I can. And only that specific file stay that way (or more than one if I keep using and if the error happen again). I wiped my log and then when the error happen this log appears: http://pastebin.com/scgktb3t . Here is the ss of the error message: http://imagebin.ca/view/AlApbbv.html .
