* It seems that the delete of the bitronix configuration file doesn't
work well (at least on my windows): The file isn't really deleted, even
if file.exists() return false. This strange behavior leads to an
AccessDeniedException when we try to open an output stream later. So,
we do not delete the file anymore, the bitronixResources.store() method
works with an overwrite behavior, there is no need to delete the file.
