Hi,

If I remove the catch(Throwable) the program crashes, which is 
why I added it in the first place :)

If I put a try {} around the dirEntries() aswell that does seem 
to catch FileException reliably.  I wonder if the Exception 
handling is being affected by the laziness of the dirEntries to 
some extent.

I'm still surprised this FileException is only being caught as a 
Throwable in this case.

I'm not sure I can create a much more simple example to test.  
Though "scanning" the C:\ProgramData\ directory and looking out 
for the Packages subdirectory should trigger the problem.  I'll 
have a bit more of a go.

Thanks
