Probably this is a Windows only problem. I tried the following 
code on my Linux machine and I didn't get any exception like 
yours:

Can you run my code just so we can confirm that the problem is in 
the Windows implementation and not in your code? Also what 
compiler version are you using? If you don't get exception while 
using your code, it would be better if you could show me a 
complete code snippet so the issue can be reproduced.
