If you read a Process.getErrorStream after the external process was killed, you get "IOException: The pipe has been ended". This bug is specific to Windows OS only.

I am attaching simple program that demonstrates this. It works fine on Solaris or on any 1.3, however it fails on 1.4 beta (62 and 63 at least)/Windows.

The program prints out whole error output of the killed process so even if "something is broken" I believe that FileDispatcher should return EOF in this case.
