was aimed to fix the problem following problem:
> Error in directory.mkdirs is masked and can result in FileNotFoundException when creating
tmp_storage directory <> 
> I verified that there is no problem in creating the parent directories, but filesystem
thinks that directory doesn't exists after it has been created succesfully. After little more
digging I stumbled upon the following:
> File.getAbsolutePath() is incorrect if "user.dir" is set on the command line <;:YfiG?bug_id=4117557>
> There is some more information about using canonical form at Mule project <>
and I found out that using getCanonicalFile() does indeed work.
> As a patch I suggest that all file/directory related methods at IOHelper would return
(canonical) File instead of String. 
> Other not so intrusive possibility would be to change XBeanBrokerService.
