Thanks for trying out that modifier. The reason it is there is to test 
out the ability to extend this part of the API with provider specific 
capabilities. My guess is that we'll need to look at this area some time 
(not jdk7 but maybe later) to see if it makes sense to add a standard 
modifier or some means to watch directories recursively. This may be 
insane in some environments but it is clear that some people are trying 
to use it this way. The hard part is dealing with errors and issues that 
arise on platforms where this isn't supported natively. I just mention 
this as one reason why this provider specific modifier could go away.
