error described in this topic thread (Unexpected RuntimeException).

Fixed issue when deleting servers. The Jabox was holding files (missing close of FileInputStream) preventing the removal of some files.

Problem reported on this topic: https://groups.google.com/forum/#!topic/users-jabox/VFHX4uZ5mJQ

Revised all locations that used FileInputStream.

I used the command "IOUtils.closeQuietly" to be a simpler implementation. As discussed here: http://stackoverflow.com/questions/156508/closing-a-java-fileinputstream
