This mostly looks good to me too, except the permission checking. As I 
read it, getInputStream uses getCanonicalFile and thus the permission 
check will be happen early and so it makes me wonder if checkRead is 
needed. Additionally, both of the uses are in privileged blocks so it 
looks like checkRead will always be called with a stack that has 
AllPermission anyway.
