Recently we start to experience following problem when running maven build:
ejb-jar.xml.unfiltered unable to be deleted

It happens only on windows and it is completly random (when you re-run the build error appears on different project). I am pretty sure that the problem is not connected to windows "nice" policy regarding file deletion since it happens also after restart. And also the file that it cannot delete is ejb-jar.xml.unfiltered that I guess is some maven temporary file.

Any help would be greatly appreciated.
